Group 0 i. Determination and compatibility of blood groups. Common health problems

For a long time, people who had the first blood group were considered universal donors. And only recently, with the discovery of new substances in the blood, scientists refuted this statement. However, in the absence of an alternative, the first negative is infused into all patients. At the same time, the 1st positive blood group is not suitable for everyone: it is also administered to patients with any group, but always with positive Rh.

The blood type is given to a person in the womb, during the formation of the fetus, and remains unchanged. What exactly it will be depends largely on the group of parents, and how exactly it was combined in the child. For example, if the mother and father have the first one, the baby will definitely inherit it. But if the blood type is different, any combination is possible.

A person’s blood type depends on the antigens on the membranes of erythrocytes (red blood cells, the main task of which is to transport oxygen and carbon throughout the body), as well as the antibodies that are produced in relation to them. Coming out of this, the AB0 system was developed, which provides for the presence or absence of antibodies and antigens in the human body. It was later found that the most common group is the first, while the rarest is the fourth.

Antigens were discovered by scientists after it became clear that blood transfusions are often fatal. During their study, such a concept as group compatibility was established: it turned out that if blood with antigens is infused into a person who does not have them, the immune system begins to produce antibodies to the foreign body that has entered the body, which leads to the death of the person.

But if, during a transfusion, you use biomaterial in which the antigens of the donor and recipient match, antibodies to them will not be developed. This means the blood is suitable and the treatment is successful.

The same applies to Rh compatibility, which implies the presence or absence of the D antigen protein on the membranes of red blood cells. Its absence is a rare case: according to what is written in statistics, the antigen protein is present in 85% of people. It does not affect health, but if it ends up in the blood, in which antigen D is absent, the recipient may die. Therefore, positive blood is not suitable for infusion in a recipient with negative Rh.

Features of the 1st group

The first blood group is characterized by the fact that it does not contain antigens A and B. Therefore, it is designated as 0 (zero), in many sources it is written as I. Due to the absence of antigens that cause an immune response, it was long believed that the first the group can be infused into any person (the main thing is that there is an appropriate Rh).

Recently, additional characteristics and properties of red blood cells have been discovered that disprove its universal compatibility. But when compared with other blood groups, the immune response is much less common, so it is still used in the absence of biomaterial with the required group.

It is worth considering that only the first group, which is Rh negative, is considered universal in terms of compatibility. Positive due to the presence of protein antigen D is not suitable for everyone, since it can only be infused into people who have it (I+, II+, III+, IV+).

But if the recipient is the owner of the first group, blood of another group cannot be transfused due to the presence of alpha and beta agglutinins in the plasma. This is the name for antibodies that the immune system produces to protect the body from foreign invasion. Therefore, it is strictly prohibited to infuse other blood groups into owners of the first group, since they contain:

• one of the antigens (in group II - A, in group III - B);
• both antigens (group IV, designated as the rarest).

As for the Rh factor, any blood is suitable for a recipient with the first positive group. At the same time, people with negative Rh need only blood that lacks antigen D: if tissue with the missing antigen enters the plasma, an immediate reaction of the body will follow.

How to calculate the group

The presence or absence of antigens A, B, D has absolutely no effect on human health. Information about group compatibility is necessary mainly during blood transfusions and during pregnancy in order to assess the risk of mismatch between the baby’s blood and the mother’s. In the course of research, it was found that if parents have different blood groups, various combinations are possible, up to the point that the baby’s group will not coincide with the parent’s. But if the mother and father have the first group, the child will have the same one.

The same applies to rhesus. If the parents do not have the antigen, the baby will have a negative group. An ambiguous answer about what the Rh factor will be if:

• the Rh factors of the mother and father do not match;
• the father and mother are positive (the possibility of negative Rh is likely if one of the ancestors had it).

Thus, if the parents do not have antigens A, B, D, the baby will have a negative first group. If Rh is present, the heir's blood can be either positive or negative.

If one of the parents has the first blood group, and the other has the rare fourth, the child will not inherit the parent’s blood group. This is explained by the fact that both antigens are absent in the blood of one parent, but present in the other. Therefore, with this combination, one of the antigens will definitely be present in the baby, while the second, most likely, will not appear. Other combinations: 1+2; 1+3 gives equal chances of whose blood the baby, mother or father will have.

Mismatch between mother and baby groups

During pregnancy, problems most often arise when there is a mismatch of Rh factors, when the mother is negative and the baby is positive. If there is no blood compatibility according to the AB0 system, although danger to the baby is possible, its probability is much lower.

This is due to the fact that the organisms of mother and child during pregnancy are closely related to each other. Therefore, there is a high probability that a situation will arise in which the baby’s blood enters the mother’s plasma. If antigens A, B, D are present on the membranes of the child’s red blood cells, while the mother does not have them, this indicates that there is no compatibility between the blood of the mother and the baby, which will lead to an immune response from the maternal body, resulting in the child's life will be at risk.

A powerful immune attack by the mother's body during pregnancy, which is provoked by a lack of compatibility, leads to oxygen starvation of the baby, so if measures are not taken in time, he may die. If he survives, he will have hemolytic disease, which may be icteric, anemic, or edematous.

Edema is considered the most dangerous, since with this disease the baby experiences an enlargement of the liver, spleen, and heart, the body will have a reduced amount of protein, and oxygen starvation will occur. These problems can cause disruption of the functioning of all organs and systems. If treatment is not started in time, this will lead to the death of the child.

Fortunately, scientists have solved this problem, so if a woman is under medical supervision during pregnancy, the problem can be avoided. There are different treatment methods to prevent the destruction of red blood cells. . If tests show that the immune system has not yet begun to produce antibodies, the woman is injected with Rh immunoglobulin twice throughout pregnancy.

If the moment was missed and the immune system began to produce antibodies, the injection should not be given at this stage of pregnancy. The doctor prescribes maintenance therapy and chooses expectant management, carefully monitoring the health of the mother and fetus. IN in severe cases, prescribes intrauterine blood transfusion to the child under ultrasound guidance. They resort to the procedure only as a last resort, since it is carried out almost blindly, the fetus and placenta are in constant motion and there is a risk of missing, hitting an artery instead of a vein, which can lead to the death of the child or severe blood loss.

The infused biomaterial must be Rh negative; if the child’s blood type has been established, it is infused; if not, blood of the first group is infused. Thanks to this procedure, the immune response is weakened during pregnancy, which improves the health of the child. Several such procedures are required, up to the thirty-fourth week of pregnancy, when the baby becomes viable and, if necessary, the doctor can decide to induce labor or perform a cesarean section.

Erythrocytes are red blood cells that have a set of individual antigenic characteristics. Their description is an interpretation of such a concept as blood type. The first positive one is the most common, so its characteristics and compatibility will be discussed below.

General information

If a person’s blood type is positive, this means that his red blood cells are completely devoid of antigens (according to the AB0 system). When a transfusion is given, the recipient (the patient who receives the blood) will not experience an antibody-antigen reaction. This characteristic has been well studied in medicine and allows saving the lives of millions of people around the world.

The first positive blood type is the most common among people: it is about 33% of all inhabitants of our planet, in some countries even half of the population.

Story

More than 400 centuries ago, our civilization began to emerge, and it was founded by people with blood type I. They were not distinguished by outstanding mental abilities, but were able to ensure high adaptation and survival of their family. Their main activity was hunting animals. In addition, our ancestors did not know how to negotiate, and disobedient members of the tribe were immediately destroyed. Some scientists believe that ancient people (whose blood type was the first positive) were the founders of omnipotence and authoritarianism.

New story

At the end of the 19th century. Australian scientist K. Landsteiner studied red blood cells. He revealed an interesting pattern - in the blood of all people there is a certain marker, which is designated A and B. Later, the scientist came to the conclusion that these are antigens that form the species specificity of cells.

Landsteiner's research made it possible to divide all of humanity into three groups. A few years later, a fourth group was discovered, thanks to the scientist Decastello. The joint efforts of two doctors made it possible to develop the AB0 system, which is still in use today.

Our children

Some parents wonder what kind of blood their children will have. Doctors note that the result depends on the genetic predisposition of the fetus to paternal or maternal properties.

You can expect to have a child with blood group I in the following cases:

• When both parents have the same group.
• If one of the parents is a carrier - group II or III, and the second - I.

If mom or dad have the fourth group, one of the antigens will definitely be transferred to the fetus. Geneticists claim that the combination of groups IV and I does not give the fetus belonging to the latter.

Rh compatibility issues

Rhesus is an additional antigen of red blood cells. Each person either has it or does not have it (for example, the first blood group is Rh positive/Rh negative). If the parents do not have the antigen, the baby will experience the same thing. Rh negative only in the mother or only in the father, the chances are 50/50.

Such compatibility is of paramount importance for the birth of healthy offspring and a successful pregnancy. In addition, such factors are taken into account when implementing blood transfusions.

Importance for the expectant mother

A woman can be calm if she has been diagnosed with the first blood group, Rh positive. In this case, the characteristics of the baby’s blood do not have any consequences for the successful pregnancy.

Without an antigen, maternal compatibility with fetal blood parameters is of particular importance, which also depends on the paternal genotype. This can initiate a Rh conflict if the fetus chooses the paternal positive gene. The cells of the female body strive to get rid of the protein, which they perceive as foreign. During the first pregnancy, the baby may be born with anemia, impaired liver function, and jaundice. During the second pregnancy, more serious consequences are possible - spontaneous abortion in the early stages, rejection of the placenta.

When parents have a positive blood type, they don’t have to worry. However, doctors recommend taking blood tests for the presence of antigen even when planning pregnancy. When the baby and the mother's body come into conflict, appropriate treatment is developed. Timely administration of anti-rhesus globulin helps bind the mother's antibodies, which contributes to successful pregnancy and the birth of healthy offspring.

Blood transfusion

Universal donors are considered to be those individuals whose blood group is first positive; The characteristic of its composition is that it does not have antigens. In emergency cases, blood transfusion can be performed on any patient, especially if the hospital does not have the required blood type.

However, if the recipient’s blood group is first positive and first negative, only single-type blood of the corresponding Rhesus is suitable for him. If another blood is infused into the patient, red blood cells will stick together. This will cause a negative reaction and complicate the weakened condition of the patient.

Plasma compatibility

Not so long ago, doctors believed that plasma transfusions could be carried out in any volume and without fear. This was the feature that distinguished the first positive blood group; compatibility with other groups was considered high. However, after a series of modern studies, scientists were able to discover that plasma contains agglutinins, which can negatively affect the patient’s health. To avoid the development of unpleasant consequences, group I plasma is diluted with the recipient’s plasma and injected into the body.

Does blood affect character?

Nature itself has endowed people with blood type I with a character aimed at overcoming difficulties. These are individuals with high strong-willed abilities who often become leaders, regardless of the environment. They do not pay much attention to the moral side of the issue, being on the way to their desires and goals.

Scientists, having carried out a number of studies, stated that such people have a heightened emotional background and a highly developed sense of self-preservation, but are unusually jealous. Strength and leadership qualities allow them to calculate all their actions and think through their own benefit. The first positive blood type in a woman indicates that she is capable of in-depth analysis of her activities and does not tolerate any criticism. Such people are suitable for high positions and positions.

Possible diseases

The following are considered typical diseases for people with blood group I:

• Arthritis, arthrosis and other joint lesions.
• Diseases of the respiratory system, predisposition to respiratory infections, tuberculosis, pneumonia, influenza.
• Deterioration of thyroid function.
• Hypertension.
• Ulcerative lesions of the digestive system.
• Men have hemophilia.

Hematologists say that patients with the first blood group suffer from coagulation disorders. They should exercise caution when taking medications containing aspirin. To preserve your intestinal microflora, it is better to take probiotics regularly.

In addition, herbal treatment works well. Decoctions of rosehip and mint have a healing effect. You should not take tinctures of burdock and aloe roots.

Diet for the first positive blood group

The principles of rational nutrition take into account all risk factors that can negatively affect their health. This food contains a selection of optimal foods suitable for their digestive system and supports typical metabolism.

Doctors note that people with blood type I are most predisposed to obesity. As a rule, the cause is a violation of nutritional standards. This opinion is supported by nutritionists.

Official medicine recognizes the rationality of this approach. It is very important to take into account a person’s genetic characteristics when implementing therapy and in everyday life.

Blood type first positive: food characteristics

• Liver, any fish (red and white), all types of meat.
• Bird and game.
• In order for protein to be fully absorbed, you should consume fish oil. It improves blood clotting parameters and is a source of Omega-3 acids.
• To avoid hormonal disorders (coming from the thyroid gland), it is recommended to consume seafood.
• For women, it is especially important to take proteins from dairy products (this is kefir and a little cheese).
• You can eat eggs, but in limited quantities.
• Among cereals, buckwheat is considered useful for people with blood group I.
• Vegetables and fruits and greens are needed in large quantities.
• The bread must be rye.
• Among drinks, preference should be given to herbal infusions and green tea.

To control weight, physical activity is recommended to help stabilize metabolism.

List of prohibited products

Nutritionists do not recommend that people with such blood consume all legumes and corn. They can be included in recipes in strictly limited quantities, but consumption as a main dish is contraindicated. Also, you should not overuse oatmeal, rice, lemons and other citrus fruits. Poor tolerance to pickled vegetables, potatoes, cabbage is possible. Sweets and coffee are subject to restrictions.

In conclusion, I would like to note: if a person has a desire to examine his blood, he can contact any of the listed doctors and receive a referral for analysis - this is a therapist, a hematologist, in some cases, an emergency doctor and a resuscitator.

Medical issues: blood group zero (I) and all the most interesting things about it. Zeroed Blood Project

The blood flowing through our vessels has certain immunogenetic characteristics. It is by these that the antigens present in this biological fluid are determined. Many of them are similar. Some are even identical. Based on their similarities, they are usually grouped into blood groups. Today it is customary to distinguish four of them. But there is information that another one will appear soon. And this will be blood of group zero. But before talking about these developments, it is worth noting the already existing 0(I).

Total information

Many people wonder: what is blood type zero? The first one, actually. It is designated in the system as follows: “AB 0:0”. Although this option is more common - 0(I).

Scientific research confirms that this blood group is the most common in the world. For a long time there were no other options on the planet. This group is the simplest in structure, which is confirmed by its chemical analysis.

A child with 0(I) can be born to parents, each of whom has 0(I). Or if at least one of them has the first group, and the second has the third or second.

Reflection on preferences

Surprisingly, a person’s first (zero) blood group affects his life (meaning the everyday level). People with the first blood group, as a rule, love meat, do not have digestive problems, have an excellent immune system and respond positively to exercise and stress. But it’s difficult for them to adapt to new living conditions.

They also say that blood type affects character. Scientists assure: this is due to the fact that our biological fluid was transformed under the influence of changes in the environment and the “legacy” of our ancestors. So, people with 0(I) are very emotional, sociable, purposeful and active. In addition to good health, they also have well-developed willpower. However, negative qualities often appear, which include hot temper, aggressiveness and even cruelty to some extent.

With a plus sign

Now it is worth considering such a moment as the Rh factor. And we will start with the “plus”. Positive zero blood group - what is its characteristic biological fluid? We will not go into the details of the chemical structure; it would be better to note its reflection on human physiology.

People with 0(I) Rh+ live longer than others, this is confirmed by research from the University of Göttingent, which proved that 60% of people over 75 years of age have a positive first group. They are resistant to neuroses and rheumatoid diseases, but are susceptible to ulcers and skin diseases. Also, people in the first positive group usually look younger than their age.

With a minus sign

Now it’s worth talking about the owners of 0(I) Rh-. If we talk about ailments, these people are susceptible to allergies, obesity and hypertension. They are also more often exposed to diseases such as pneumonia, tuberculosis, influenza, and ARVI. They have weak immunity. These people are also very strong-willed, but they can be narcissistic, overly jealous and intolerant of criticism. What about the pros? Holders of 0(I) Rh- have a well-developed sense of self-preservation. Perhaps, among the positive things about the named owners, the “negative” is all.

Here, however, is all the general information about the biological “category” known as 0(I). But is there a zero blood type under the usual designation “0”? Let’s talk about this in a little more detail.

Donation problem

Unfortunately, cases often occur that require blood transfusions. But not all groups and Rh factors are compatible. For a person with the first negative, for example, only identical blood is suitable. And the owner of the fourth negative can receive any transfusion - he is a universal recipient.

The bottom line is that the incompatibility of different groups leads to problems associated with donation - not everyone who needs it can be saved. And scientists believe that if we create universal blood of group zero, the issue will be resolved.

But this is a very serious task. It is necessary to remove agglutinogens from it, which glue red blood cells together. Various attempts were made for this - coffee beans, which drive away agglutinogen B, and various bacteria were used. Currently, scientists are working on creating a device that could create type zero blood from any other.

Research

Naturally, doctors would not have such ideas without compelling reasons. But they exist. Type 0 blood is not just a project, but a theory supported by research. However, little is known about them. But there is information that certain observations have been carried out over the course of 20 years.

Doctors regularly interviewed patients who, by their consent, had been transfused with “nullified” blood. They were about 27,500 men (from 40 to 75 years old) and more than twice as many women (from 30 to 55). Analyzes were performed using a log stepwise test. Age, attitude towards nicotine and alcohol, body weight index, history of hereditary diseases and, in particular, the presence of coronary heart disease, diabetes or high cholesterol in any relatives were taken into account.

Is there a zero blood group now, is blood transfusion practiced? It is safe to say that the research is not completed. And it is unlikely that there will be a result soon. At the moment, the safety of using current developments is not 100% ensured. Therefore, we can only wait for progress and believe in science.

How many blood types are there? What does blood type mean, compatibility, features

About 5 liters of blood continuously circulates in the body of an adult. From the heart it is carried throughout the body by a fairly branched vascular network. The heart needs about a minute, or 70 beats, to pump through all the blood, which supplies all parts of the body with vital elements.

How does the circulatory system work?

It delivers oxygen received by the lungs and nutrients produced in the digestive tract to where they are needed. Blood also transports hormones to their destination and stimulates the removal of waste products from the body. The lungs are enriched with oxygen, and carbon dioxide is released into the air when a person exhales. It transports cell breakdown products to the excretory organs. In addition, the blood ensures that the body always remains uniformly warm. If a person has cold feet or hands, it means they have insufficient blood supply.

Red blood cells and white blood cells

These are cells with their own special qualities and “tasks”. Red blood cells (erythrocytes) are formed in the bone marrow and are constantly renewed. There are 5 million red blood cells in 1 mm3 of blood. Their job is to deliver oxygen to different cells throughout the body. White blood cells - leukocytes (6-8 thousand per 1 mm3). They inhibit pathogens that have entered the body. When the white cells themselves are affected by the disease, the body loses its protective functions, and a person can even die from an illness such as influenza, which can be quickly overcome with a normal defense system. The white blood cells of an AIDS patient are affected by the virus - the body can no longer resist the disease itself. Each cell, leukocyte or erythrocyte is a living system, and its vital activity reflects all the processes occurring in the body.

What does blood type mean?

The composition of blood differs among people, just like appearance, hair and skin color. How many blood types are there? There are four of them: O (I), A (II), B (III) and AB (IV). Which group a particular blood belongs to is influenced by the proteins contained in red blood cells and plasma.

Antigen proteins in red blood cells are called agglutinogens. Plasma proteins are called agglutinins. There are two types of agglutinogens: A and B, agglutinins are also divided into a and b.

That's what's happening. Let's take 4 people, for example, Andrey, Alla, Alexey and Olga. Andrey has blood type A with A agglutinogens in his cells and agglutinins in his plasma. Alla has group B: agglutinogens B and agglutinins a. Alexey has group AB: the peculiarities of blood group 4 are that it contains agglutinogens A and B, but no agglutinins at all. Olga has group O - she does not have agglutinogens at all, but there are agglutinins a and b in her plasma. Each organism behaves with other agglutinogens as if it were a foreign aggressor.

Compatibility

If Andrey, who has type A, is transfused with blood of type B, its agglutinins will not accept the foreign substance. These cells will not be able to move freely throughout the body. This means they will not be able to deliver oxygen to organs such as the brain, and this is life-threatening. The same thing happens if you connect groups A and B. Substances B will repel substances A, and for group O (I) both A and B are not suitable. To prevent errors, patients are first tested for their blood type before transfusion. People with blood group I are considered the best donors - it is suitable for anyone. How many blood groups exist - they all positively perceive blood of type O; it does not contain agglutinogens in the red blood cells, which might not be “liked” by others. Such people (like Olga in our case) are universal donors. Group AB contains both A and B proteins and can combine with the others. Therefore, a patient with blood group 4 (AB), with the necessary transfusion, can safely receive any other. That's why people like Alexey are called "universal consumers."

Nowadays, when transfusing a patient, they try to use exactly the blood group that the patient has, and only in emergency cases can the universal first be used. In any case, it is first necessary to check them for compatibility so as not to harm the patient.

What is the Rh factor?

Some people's red cells contain a protein called Rh factor, so they are Rh positive. Those who do not have this protein are said to have a negative Rh factor and are only allowed to receive blood transfusions of exactly the same type. Otherwise, their immune system will reject it after the first transfusion.

It is very important to determine the Rh factor during pregnancy. If the mother has the second negative group, and the father has a positive group, the child may inherit the father’s Rh factor. In this case, antibodies accumulate in the mother's blood, which can lead to the destruction of red blood cells. The second positive group of the fetus creates an Rh conflict, which is dangerous to the life and health of the child.

Genetic transmission of the group

Just like the shade of hair, a person inherits blood from his parents. But this does not mean at all that the child will have the same composition as both or either of the parents. Sometimes this issue unknowingly becomes the cause of family quarrels. In fact, blood inheritance is subject to certain laws of genetics. The table below will help you understand what and how many blood groups exist during the formation of a new life.

For example, if the mother has type 4 blood and the father has type 1, the child will not have the same blood as the mother. According to the table, he may have both a second and a third group.

Inheritance of a child's blood type:

The Rh factor is also inherited. If, for example, both or one of the parents has a second positive group, then the baby can be born with both positive and negative Rhesus. If each parent is Rh negative, then the laws of heredity come into play. The child may have the first or second negative group.

Dependence on a person's origin

How many blood groups exist, what their ratio is among different peoples, depends on their place of origin. With so many people taking the blood typing test around the world, it has provided researchers with the opportunity to track how the frequency of one or the other varies depending on geographic location. In the United States, 41% of Caucasians have type A blood, compared to 27% of African Americans. Almost all Indians in Peru have group I, and in Central Asia the most common is group III. Why these differences exist is not entirely understood.

Susceptibility to certain diseases

But scientists have noticed some interesting connections between blood cells and some diseases. Those with blood type I, for example, are more at risk of developing ulcers. And people with the second group are at risk of developing stomach cancer. This is very strange, but the proteins that determine the composition of the blood are very similar to the proteins found on the surface of certain pathogenic bacteria and viruses. If a person becomes infected with a virus with surface proteins similar to their own, the immune system may perceive them as its own and allow them to multiply unhindered.

For example, the surface proteins of the microorganisms that cause bubonic plague are very similar to the proteins of blood group I. Scientific researchers suspect that such people may be especially susceptible to this infection. Scientists believe the disease originated in southeast Asia and spread westward. When it reached Europe, it destroyed a quarter of its population in the 14th century: the disease was then called the “Black Death.” Central Asia has the smallest population with blood type I. Therefore, it was precisely this group that was the “disadvantage” in areas where the plague was particularly rampant, and people with other groups had a better chance of survival. Scientists believe that there is a dependence of diseases on the composition of the blood. Studying this version will help in the future to decipher the genesis of diseases and reveal the secrets of human survival.

What does blood type 0 (1) RH FACTOR + mean to me? pregnancy test

Laura

According to some American scientists, the first blood group, which has the official designation 0(I), is the most common and the oldest.
Our ancient ancestors, who lived millions of years ago, were forced to constantly fight for survival, and this struggle formed an intelligent and dexterous hunter, possessing qualities that remain indispensable even today in the 21st century in any social environment. What are these qualities? These include leadership, exgravation and the ability to concentrate all forces to achieve a goal. Extroversion is a personality type characterized by a predominant focus of activity, attitudes, aspirations and interests on the outside world and the people around them. But these qualities of a person in modern society, depending on the goals pursued by the individual, can be very dangerous for members of society itself. On the one hand, a person with blood type I can be an excellent organizer, leader, talented worker, and inspirer of ideas. However, this same personality, with its characteristic psychological characteristics, in extreme situations can acquire a different direction, and then instead of an inspiring leader, a tyrant leader appears, and if he has power, he begins the deadly game “kill so that they don’t kill you” - a game that is especially dangerous in modern society.
Unbalanced owners of this blood type can react to stress with increased activity, often with attacks of anger, outbursts of irritation, and even a manic attack, which are a consequence of serious biochemical changes caused in the body. (It should be pointed out that among people with blood type I there are many gamblers, thrill-seekers and risk-seekers, alcoholics and drug addicts, as well as individuals prone to impulsive actions.)
Taking into account all that has been said, a person living in a modern civilized society, a “carrier” of the first blood group, must be able to successfully consolidate and develop genetically determined advantages, and disadvantages must be able to control and, if possible, eliminate. Taking all this into account, the main goal of an individual with blood type I in modern conditions becomes clear - the need to master the physiological advantages inherited from distant ancestors, and to control their shortcomings. You are created for creative, productive and effective activities, and not destructive for society.

Blood groups, compatibility and inheritance

Blood consists of a liquid part - plasma and various blood cells (formed elements). Plasma contains proteins, minerals (main composition: sodium, potassium, calcium, magnesium, chlorine) in the form of ions and other components. Formed elements of blood - erythrocytes, leukocytes, platelets. Blood volume is 6-8% of body weight - about 5 liters. Blood performs a number of important functions: transports oxygen, carbon dioxide and nutrients; distributes heat throughout the body; ensures water-salt metabolism; delivers hormones and other regulatory substances to various organs; maintains the constancy of the internal environment and has a protective (immune) function.

Differences between people in blood groups are differences in the composition of certain antigens and antibodies.

The main blood classification system is the ABO system (read - a, b, zero)
Blood groups are designated by the presence or absence of a certain type of “gluing” factor (agglutinogen):
0 (I) - 1st blood group.
A (II) - 2nd.
B (III) - 3rd
AB (IV) - 4th blood group.

The Rh factor is an antigen (protein) found in red blood cells. Approximately 80-85% of people have it and are therefore Rh positive. Those who do not have it are Rh negative. It is also taken into account during blood transfusions.
Whole blood transfusions, taking into account groups, are carried out only according to the principle of the same group (for children this rule is mandatory). The blood of a group 0 (I) donor can be transfused into a group 0 (I) recipient, and so on. In emergency situations, when there is no time or opportunity to do an analysis, it is permissible to transfuse blood of group I “negative” to recipients of other groups (“until clarification”), since blood group 0 (I) is universal. In this case, the portion of injected blood is limited to a minimum volume. Taking into account the Rh factor, you cannot transfuse a “positive” one if the recipient is “negative” (this is fraught with Rh conflict). It’s the same when conceiving a child - if the mother is “negative,” and the father is Rh positive.

Mother

Father

Based on the table above, paternity (or denial of paternity) can be established based on the child’s blood type.
Inheritance of blood type and Rh factor occur independently of each other. If both parents are Rh positive, the child will only be Rh positive. If both parents have a negative – the child inherits more often - deny. If one of the parents is Rh positive and the other is Rh negative, then the probability of the baby being Rh is determined to be 50% to 50%. There is a possibility of inheriting Rhesus after several generations (the case when the father and mother have a positive Rhesus, and the born child has a negative Rhesus). Parental compatibility tests are required for women with Rh-neg. blood - a risk group, if the fetus is "positive" (to exclude Rh conflict between the mother and the fetus, antibodies are produced against the fetus).
Less commonly, hemolytic disease of the newborn is caused by group incompatibility (group) of the blood of the mother and fetus. Immune incompatibility manifests itself when the mother has blood group I, and the fetus has blood group II, or less often III.
During pregnancy, in a woman with Rh-negative blood, it is necessary to determine the titer of Rh antibodies in the blood over time.

Blood type A (II). Diligent and obligatory. They love harmony and order. Their weakness is stubbornness.

Blood type B (III). Delicate, impressionable, calm. Increased demands on yourself and others. Individualists. They adapt to everything easily. Powerful and creative personalities.

Blood type AB (IV). Emotions and feelings take precedence over common sense and calculation. They are thinkers. They have difficulty making decisions. Balanced, but sometimes harsh. Most of all they conflict with themselves.

There is a pattern between blood type and the risk of developing certain diseases (predisposition). Australian scientists have found that people with blood type 0 (I) are much less likely to suffer from schizophrenia. Those with type B (III) blood have a higher risk than others of a severe nervous system disease - Parkinson's disease. Of course, the blood type itself does not mean that a person will necessarily suffer from a disease “characteristic” of it. There are many factors involved, and blood type is just one of them.

Diseases of the gastrointestinal tract

People with the first blood group (it is the most common among Europeans) have a predisposition to peptic ulcers of the stomach and duodenum. Having the first blood group increases the risk of developing stomach and duodenal ulcers by 35% compared to people with other blood groups.

The second blood group is a predisposition to gastritis with low acidity. People with this blood type are also more vulnerable to the formation of stones in the bile ducts, they often develop chronic cholecystitis (inflammation of the gallbladder), but it is rare for them to develop peptic ulcers.

The third blood group is predisposed to colon tumors.

Blood group 4 - resistant to peptic ulcers.

Dental caries

It has been established that caries most often occurs in people with the second and third blood groups.

These people are carriers of genes associated with a predisposition to developing this disease.

Caries is rarely found in people with the first blood group. People with AB blood group IV, especially women, are also resistant to caries. They have a minimal risk of caries and a more favorable course of this disease.

In persons with the second blood group, the development of the pathological process in the hard tissues of the tooth is acute (rapidly progressive). In a short period of time, caries affects a large number of teeth.

In people with the third blood group, despite the high risk of developing caries, the course of the disease is more favorable (it develops slowly and is treatable).

Diseases of the cardiovascular system

People with blood group O have the highest risk of developing hypertension.

The second blood group is a predisposition to the development of coronary disease, acquired mitral heart disease, as well as congenital heart disease when all four heart valves are affected. Many heart diseases, including heart defects, arise as a result of rheumatism. Persons with the second blood group are prone to rheumatism and myocardial infarction.

The third group is resistance to myocardial infarction.

People with the second and fourth blood groups have a high risk of increased cholesterol levels, and are more likely to develop atherosclerosis and heart disease, and obesity. In addition, people with the second and fourth blood groups experience diseases associated with increased blood coagulation: thrombosis, thrombophlebitis, obliterating endarteritis of the lower extremities.

Tumors

In people with the first blood group, colon cancer (tumor) is rare, and the prognosis of the disease is often favorable.

The second blood group determines a predisposition to the development of stomach cancer and acute leukemia (“leukemia”, “blood cancer”).

The third group is a predisposition to colon cancer.

Diseases of the blood system

The predisposition of people with the first blood group to hemophilia has been established.

The second blood group is a predisposition to acute leukemia.

Thyroid diseases

Thyroid diseases are more common in people with blood group II.

Mental illnesses, as well as conditions close to them

Among patients with schizophrenia, the smallest number of patients have the first blood group.
While among people with the third and fourth blood groups, patients suffering from neuroses and psychoses are relatively common.

Diseases of the kidneys and genitourinary system

People with the first and second blood groups are most predisposed to developing kidney stones. The first blood group is identified by nephrologists as the highest risk factor for developing this disease.
Women with the third blood group are most susceptible to frequent urinary tract infections (especially if the infection is caused by E. coli, since there are similarities between the structure of the antigens of E. coli and the third blood group). People with the fourth blood group are most resistant to the development of kidney diseases.

Skin diseases

People with the first blood group, especially those with negative Rh, are more likely to suffer from skin diseases.

Skin diseases are less common in people with blood group IV.

Infectious diseases

People with blood type O are more likely to get influenza A.

Lung diseases

Individuals with blood group 0 (I), especially those with negative Rhesus, are most predisposed to developing diseases of the bronchi and lungs. Among them, the leading ones are pulmonary tuberculosis, chronic allergic bronchitis, allergic conditions accompanied by pathology of the bronchial system, and bronchial asthma.

People with the fourth blood group are least susceptible to lung diseases (pneumonia, bronchitis).

For spouses, determine blood groups and Rhesus. A positive Rh factor in a woman and a negative Rh factor in a man do not represent any cause for concern. If a woman has Rh-negative blood, and her husband has Rh-positive blood, then during pregnancy a Rh conflict may develop, so the woman is recommended to do a blood test for antibodies to the Rh factor before pregnancy. The fact is that if a woman underwent surgery (including abortion) or blood transfusion before pregnancy, or if this is not her first pregnancy, then there is a possibility that specific antibodies will form in her blood. In a Rh-negative woman with a Rh-positive fetus, immune complications (hemolytic disease of the newborn, etc.) are possible, and especially from the second or third pregnancy. To prevent complications, anti-Rhesus gamma globulin is administered. It is necessary to regularly test your blood for Rh antibodies.

Consider the Rh factor when receiving blood transfusions. Rh conflict can develop with repeated transfusion of Rh-positive blood to persons with Rh-negative blood. Women with the first blood group are also a risk group. By the way, the future father must also take a blood test to determine his blood type and Rh factor. This test shows whether you and your baby are at risk due to a conflict between your blood types or Rh factors. Taking a blood test for iron will help prevent anemia, which often occurs during pregnancy. If necessary, your doctor will prescribe you iron supplements.

Health

Our blood type has a big impact on our body along with our diet and lifestyle. As you know, there are 4 types of blood groups: I (O), II (A), III (B), IV (AB).

A person's blood type is determined at birth and has unique characteristics.

All blood types have several characteristics that interact with each other to determine how external influences affect our body. Here are a few facts that would be interesting to know about blood type.

1. Nutrition according to blood type

Throughout the day, chemical reactions occur in our body, and therefore blood type plays an important role in nutrition and weight loss.

People with different blood types should eat different types of food. For example, people with blood type I (O) it is worth including protein-rich foods in their diet such as meat and fish. People with Blood type II (A) should avoid meat, since vegetarian food is more suitable for them.

To those who III (B) blood type, you should avoid chicken meat and consume more red meat, and people with IV (AB) group will benefit more from seafood and lean meat.

2. Blood type and diseases

Because each blood type has different characteristics, each blood type is resistant to certain types of diseases, but is more susceptible to other diseases.

I (O) blood group

Strengths: resilient digestive tract, strong immune system, natural defense against infections, good metabolism and nutrient retention

Weak sides: bleeding disorders, inflammatory diseases (arthritis), thyroid diseases, allergies, ulcers

II (A) blood group

Strengths: adapts well to dietary and environmental diversity, retains and metabolizes nutrients well

Weak sides: heart disease, diabetes type 1 and 2, cancer, liver and gallbladder diseases

III (B) blood group

Strengths: strong immune system, good adaptability to dietary and external changes, balanced nervous system

Weak sides: type 1 diabetes, chronic fatigue, autoimmune diseases (Lou Gehrig's disease, lupus, multiple sclerosis)

IV (AB) blood group

Strengths: well adapted to modern conditions, stable immune system.

Weak sides: heart disease, cancer

3. Blood type and character

As mentioned earlier, our blood type also affects our personality.

I (O) blood group: sociable, confident, creative and extroverted

II (A) blood group: serious, neat, peaceful, reliable and artistic.

III (B) blood group: dedicated, independent and strong.

IV (AB) blood group: reliable, shy, responsible and caring.

4. Blood type and pregnancy

Blood type also affects pregnancy. For example, women with blood type IV (AB) produce less follicle-stimulating hormone, which helps women get pregnant more easily.

Hemolytic disease of newborns occurs when the blood of mother and fetus is incompatible with the Rh factor, sometimes with other antigens. If an Rh-negative woman has a fetus with Rh-positive blood, an Rh conflict occurs.

5. Blood type and exposure to stress

People with different blood types react differently to stress. Those who lose their temper easily are most likely owners of blood type I (O). They have higher adrenaline levels and take longer to recover from a stressful situation.

At the same time, people with blood type II (A) have higher levels of cortisol, and they produce more of it in stressful situations.

6. Blood group antigens

Antigens are present not only in the blood, but also in the digestive tract, in the mouth and intestines, and even in the nostrils and lungs.

7. Blood type and weight loss

Some people have a tendency to accumulate fat in the belly area, while others may not worry about it due to their blood type. For example, people with blood type I (O) are more prone to fat in the abdominal area than those with blood type II (A), who rarely experience this problem.

8. What blood type will the child have?

At the present stage, several antigenic systems of erythrocytes have been discovered in humans - specific sets of proteins and polysaccharides that are elements of the cell wall of red blood cells and are responsible for compatibility.

According to the AB0 system, the entire human population can be divided into 4 groups:

• the first group of our blood - antigen 0 (zero) - proteins α and β in the plasma;
• the second - antigen A - protein β in plasma;
• third - antigen B - protein α in plasma;
• fourth - antigens A and B - there are no agglutinin proteins α and β in the plasma.

Biochemical characteristics

By their structure, antigens of the AB0 system are glycoproteins and are found in all tissues of the human body, excluding the brain. They have the main practical significance, being located in the membrane of cells that carry oxygen - red blood cells. The genes that encode the synthesis of these compounds are located in a locus on the long arm of chromosome 9; they encode antigens A¹, A², B and 0.

Human blood group zero in the AB0 system stands somewhat apart. The features of this variety are the absence of strong antigens A and B on red blood cells and the presence of weak antigen 0, the presence of antibodies - agglutinin proteins α and β in the plasma.

Previously, people with such antigen characteristics were considered universal donors (especially blood group 1 Rh-negative), which supposedly means that transfusion of their blood is possible for all people. This property is now used only in special conditions and in limited quantities. It was found that during blood transfusion of the first group, signs of incompatibility may appear due to the fact that agglutinins α and β present in the zero group glue the recipient’s red blood cells containing antigens A and B.

How can the Rh factor affect

The Rh factor is another, second most powerful and important antigenic system of tissue compatibility of erythrocytes. During the initial determination, the first positive is recorded in medical documents as 0 (I) Rh +. This means that red blood cells with a zero antigen according to the AB0 system carry a Rh-positive antigen.

In the opposite case, when blood group 1 is negative, the analysis form will write 0 (I) rh -, that is, negative for the Rh factor.

Transfusions to Rh positive recipients are always carried out with the same type of donor red blood cells. Otherwise, if Rh compatibility is not taken into account, severe post-transfusion complications, agglutination and hemolysis (destruction of red blood cells) with dangerous consequences for the body, such as transfusion shock and acute renal failure, are possible.

Compatibility

Blood group 0 as a donor can be transfused to a recipient with any group. If a patient who needs blood transfusion has such blood, then he can only receive a blood transfusion of the first group.

However, this rule only applies in extreme situations. In modern medical practice, the selection of donor blood must be of the same group, the same Rh factor, and also matching the maximum number of antigenic systems (phenotype).

The first negative in men is a rare group, as well as in women. The presence of a negative Rh factor in women when planning a pregnancy is decisive.

A donor is a person who donates his blood for transfusion or organs for transplantation to other people. Since blood is a tissue of the human body, the general principles of transfusiology are similar to transplantology.

Any adult with suitable health conditions can be a donor of blood and its components. Donors' blood is examined for infections, red blood cells are placed in a special preservative solution and sent to medical institutions for transfusion to patients.

1 positive group of donor blood can only be transfused to a recipient with the same group and Rh factor.

Before transfusion, the recipient needs to determine the group and Rh factor, regardless of how many times they have been determined for him previously. Phenotyping is carried out - selection of the donor dose taking into account all possible antigens.

Immediately before the blood transfusion, the doctor once again checks the group of the recipient and the donor, after which a test is carried out for individual group compatibility - the recipient's serum and red blood cells from a dose of donor blood are mixed in proportions of 10 to 1, the presence of agglutination (sticking together) of red blood cells is visually assessed. Rh compatibility is also checked according to accepted methods.

At the beginning of intravenous administration of a donor dose of erythrocyte-containing medium, a biological test is performed: erythrocytes are infused three times in small portions at time intervals to assess the patient’s individual response to the transfusion.

Pregnancy problems

Blood group 0 (1) in a woman with various variants of the child’s father’s group can give the following possible results.

1. Father 0 (1) - the child can only have 0 (1).
2. Father A (2) - the child will be born with group 0 (1) or A (2).
3. Father B (3) - the child will be identified as group 0 (1) or B (3).
4. If the child’s father has group AB (4), then the child has groups A (2) and B (3).

A negative maternal blood type can lead to a problem during pregnancy described as Rh incompatibility.

The problem occurs when the mother's Rh factor is negative and the child's is positive. During the first such pregnancy, no difficulties arise, however, during childbirth, the blood of the mother and child partially mixes and the woman develops antibodies to the Rh antigen. In the second pregnancy, if the baby is again Rh positive, the mother's antibodies pass through the placenta and affect the baby's tissues.

The baby develops anemia, jaundice, and in severe cases, due to decreased albumin synthesis, dropsy and edema syndrome, which complicate pregnancy until the death of the child.

Prevention of Rh conflict is carried out by intramuscular injection of special antibodies-immunoglobulins Rho GAM to the mother at 28 weeks; if necessary, the injection is repeated at 34 weeks of pregnancy.

People at this historical stage were characterized by a lifestyle associated with hunting, and the correct diet of people with this type of red blood cells should contain the following foods:

1. Meat products. Beef, offal, and lamb are healthy. Pork and goose are not recommended.
2. Seafood and fish. Recommended are seaweed, brown algae, sturgeon, pike, salmon, cod, mackerel. Smoked salmon, salted herring, and caviar are undesirable.
3. Dairy products are undesirable. Sheep cheese and cottage cheese are acceptable in small quantities.
4. Greens and vegetables. Turnips, rutabaga, artichoke, spinach, parsley, leaf beets, and kohlrabi are useful. Potatoes, corn, olives, champignons, cauliflower, white cabbage and Brussels sprouts are not recommended.
5. Fruits and berries. You can have figs, prunes, plums, apples. It is better not to eat citrus fruits, melon, avocado, strawberries.
6. Of the nuts, walnuts are beneficial for the body. It is better to avoid coconut, pistachios, peanuts.
7. It is better to exclude cereals from the diet, especially oatmeal. Barley, pearl barley, and buckwheat are neutral.
8. Bread in small quantities is only rye. Exclude pasta and baked goods.
9. For sweets - honey, chocolate, jam, sugar in small quantities.
10. Olive oil is useful. It is better not to eat corn, peanut, soy, or cottonseed.
11. Among the spices, curry and hot pepper are useful; cinnamon and nutmeg are not needed.
12. Beverages. Cherry and pineapple juice are recommended. You can have some red and white wine, green tea. Coffee, black tea, lemonades, citrus and apple juices, strong alcohol are prohibited.

Advantages and disadvantages

If we talk about the positive qualities of having blood group 1, then this is a type of antigenic properties of red blood cells that is often found in the population. About 30% of the inhabitants of our planet have it. It follows that it is quite easy to find a compatible donor if necessary.

The membrane of red blood cells contains varying amounts of proteins, as well as carbohydrates, which are called antigens. The characteristics of the blood will depend on their presence. The most numerous is blood group 1 with a positive Rh factor.

Attention! Rh factor is an indicator of the antigen that is contained on the surface of red blood cells.

Initially, the 1st positive group was designated as the letter C, then it was decided to prescribe 0, that is, thus indicating that there were no antigens in the blood. On the contrary, the presence of antigen H can be found on the surfaces of red blood cells, as well as in other tissues of the body. Rh positive is assigned to this blood group due to confirmation of the presence of antigen D in the owners.

It should be noted that blood retains its original characteristics (group and Rh) throughout life. Group 1 can be inherited by a child from one or both parents. Only if the parents do not have blood type 4. It should be noted that the first positive one can be used as universal donor blood for the transfusion procedure. There will be no group incompatibility if Rh is “+”. If a person is injected with Rh negative blood, the result will be the sticking of red cells, that is, red blood cells, with subsequent deterioration of the person’s condition.

How can the Rh factor affect?

One of the most important characteristics of blood is the Rh factor. As mentioned, this is an indicator of the presence of antigen on the surface of red blood cells. To put it simply, this is an indicator of protein on the surface of red blood cells. Most people are characterized by the presence of antigens and, accordingly, have a positive Rh factor; other people are characterized by their absence, so they have a negative Rh factor.

The Rh factor is very important in two cases:

1. During the period of bearing a child, incompatible Rhesus may be life threatening.
2. If surgery is performed, which may involve a blood transfusion.

All other aspects associated with Rh a priori do not affect the state of the body, and therefore have no significance.

Pregnancy and blood compatibility

It is very important to plan your pregnancy, because blood compatibility during this period occupies a special place in the birth of a healthy baby. When both parents have a negative or positive Rh, the child will accept the same one as his parents, therefore, there will be no problems. The situation is similar with the acquisition of a blood type from parents. Studies have shown that babies often acquire their mother's blood type. Based on this, if the mother is carrier I positive, then there is a 90% chance that the baby will also be a carrier of this blood type, regardless of what blood type the father has.

Can there be a Rh conflict?

During pregnancy, the occurrence of a problem such as Rh conflict cannot be ruled out. It does not mean a combination of the parents’ Rhesus: for example, the mother’s is positive, and the father’s is negative. In this case, the child can acquire both negative and positive Rhesus. If the child takes the mother's blood, then the pregnancy promises to be without problems.

Attention! A pregnancy complication occurs when the child has a positive Rh factor and the mother has a negative Rh factor. Then a conflict between the blood of the fetus and the mother arises, which can lead to various serious complications during pregnancy.

Rh incompatibility has dangerous consequences. This is explained by the fact that antibodies produced by the mother’s body can destroy the fetus. In half of the cases, the baby acquires a positive Rh, but if the mother is negative, then there is a danger of miscarriage or intrauterine death of the fetus.

How are blood types compatible?

Until recently, experts believed that plasma transfusion occurs without consequences in any quantity. The compatibility of the first positive with other groups was excellent. However, after a number of studies, it turned out that plasma contains agglutinins, and with frequent transfusions, the likelihood of a negative effect on human health increases. Based on this, it was decided to dilute group I plasma with recipient plasma, and only after that proceed with the transfusion procedure in order to avoid possible complications.

Possible diseases

Those with a positive blood group suffer least from serious illnesses and therefore live longer than others. However, they may be predisposed to gastric ulcers due to high acidity. There is a high probability of inflammation of the gallbladder and liver. Women may be at risk for skin tumors. But, despite the above ailments, carriers of the first group are very resistant to nervousness, therefore they suffer least from mental disorders and retain a youthful brain much longer.

Reference! Among the carriersBlood group I with a positive Rh factor is extremely rare in people suffering from schizophrenia.

Based on medical research, it has been found that people with the first blood group suffer from typical diseases:

1. Pathological lesions of the joints. Arthrosis and arthritis.
2. Prone to persistent seasonal ARVI.
3. Respiratory diseases.
4. Thyroid dysfunction.
5. Hypertonic disease.
6. Ulcerative lesions of the gastrointestinal tract.
7. Hemophilia among men.

Information about diseases depending on blood type is contained in the video.

Video - Blood type and diseases

1. Poor blood clotting - this is the statement made by hematologists. Therefore, it is very important to take medications that contain aspirin, which thins the blood, with caution.
2. There may be problems with the intestinal microflora, therefore, it is best to take probiotics as a preventive measure.
3. Herbal decoctions (mint and rosehip) have a positive effect on the body. But it is recommended not to use aloe and burdock root.

Proper nutrition

The health status of each person is primarily affected by diet. After all, the food of the daily diet should contain a set of products that have a positive effect on metabolism and the digestive system as a whole.

It was found that carriers of I positive tend to be overweight. The gain of extra pounds occurs due to a violation of proper healthy nutrition. Since time immemorial, people with I positive have been hunters, so their diet should consist largely of natural proteins. This statement was recognized even by official medicine. Consequently, it was established list of necessary products for people withI blood group.

It is necessary to adhere to dietary features, since people with the first blood group are prone to diabetes.

Note! In general, for normal well-being, owners of all blood groups are recommended to adhere to proper nutrition and lead a healthy lifestyle (with mandatory sports activities), but for people with blood groupsIf you have a positive Rh factor, you should base your diet on foods high in protein.

It is known that foods rich in protein can, in small quantities, quickly relieve hunger and completely saturate the body. In addition, they support the normal metabolic process. Mostly protein-containing foods are all types of meat, especially dark meat. Particular attention should be paid to the liver, as an offal for cooking, which contains a sufficient amount of protein.

To avoid problems with the functioning of the thyroid gland, you should regularly eat seafood, which contains the required amount of iodine.

Attention! It should be recalled that it is the thyroid gland that is most often vulnerable in people with blood typeRh positive.

When planning a diet, it is necessary to take into account your blood type, so when the first blood type is positive, it is recommended to consume goji berries; you can find out more here.

Can blood affect a person's character?

According to statistical data, it was found that the owners of the first positive character have a persistent character, are self-confident, know how to set goals for themselves and go towards them without losing their way. The general characteristics show that those with blood group I have strong willpower, so there are quite a lot of leaders among them.

Scientists have added to the psychological portrait of such people increased emotionality, excessive jealousy and an increased level of self-preservation. Self-confidence, supported by leadership qualities, helps to calculate actions and steps in advance, while simultaneously determining your benefits.

Women with blood type I constantly analyze their activities and categorically do not accept criticism in their direction. Most often they occupy high positions. A professional psychologist will tell you in a video about how blood type affects a person’s character and determines fate. study on our website.
