Do you know how our blood cells are formed? What’s your blood type? How are blood groups classified? Here we are going to discuss all blood groups and how they are classified on what basis.
Blood is a body fluid that passes throughout the body by the pump activation of the heart. Blood is thicker than the water. It carries oxygen to the cells and in return receives metabolic waste to remove them from the body. It contains hemoglobin pigment which is having iron in it, responsible for making blood color red. The color of blood is also different in some vertebrates due to absences of hemoglobin; it is also known as white blood cells. Blood is carrying eight percent of the total body weight of the living organism.
When a person meets with an accident, doctors will ask what the blood group of the person is. So, what’s the importance of knowing the blood group when we are injecting blood to him. Do we really need to inject the same blood group? We will get all the answers to all these questions.
Blood groups are classified based on the presence and absence of antigens and antibodies in the body of living organisms. We can also call them blood type. When we want to donate blood or receive the blood we have to know the blood group priorly. Blood group testing will be done in order to get to know the blood type.
The blood group antigens are not strictly restricted to red blood cells or hematopoietic tissues. A common blood type is permanent to all living organisms but in rare cases, the blood group type changes like bone marrow transplantation. While doing this transplantation the receiver will get the blood type of donor because the receiver’s bone marrow is destroyed as well as hematopoietic tissues from which blood cells are derived.
The four main types of blood groups are A, B, AB, and O. These are determined by the presences or absences of two antigens on the surface of red blood cells, those two antigens are A and B. These antigens may be proteins, carbohydrates, glycoproteins or glycolipids depending on the blood group system of the living organism. Blood types are inherited and show a contribution from both parents.
In 2019 International Society of Blood Transfusion recognized 41 human blood groups and in all of them, the major dominating blood groups are ABO and Rh blood groups by which the blood group is decided at the time of blood transfusion.
Blood types were first discovered by Karl Landsteiner in 1900.
This classification is mainly based on the presence and absence of antigens on the surface of red blood cells. If a person is having antigen A on the surfaces of red blood cells then the person has A Blood group. Instead of A if an RBC has B antigen on the surface then the person is said to be having B type, blood group. If a person has both antigens on the surface of red blood cells then the group of people is AB and if they don’t have either A or B antigens, the person’s blood type is O.
And also antibodies are responsible for this classification. Antibodies are present in serum.
Between antibodies and antigens, agglutination reaction occurs like antigen A agglutinates the antibody A and same in the case of B antigens shows agglutination with B antibodies. So this is the reason that we have to carefully observe at the time of blood transfusion. Transfusion can be considered safe as long as the serum of the recipient does not contain antibodies for the blood cell antigens of the donor.
The full form of Rh is Rhesus, which is the second most important blood group system in human blood which currently has 50 antigens. The main antigen in rhesus is the D antigen as it mostly provokes an immune system response of the five main Rh antigens. The person having D negative won’t have any antibodies of D. It is not a common blood type group. It is one of the rare blood groups in humans. If a person has Rh factor on red blood cells then he or she has an Rh-positive blood group. The absence of the Rh factor on red blood cells leads to an Rh-negative type blood group.
This area explains to us the blood group and what’s the importance of knowing the blood group of a human before transfusion is very crucial for getting high marks. It’s a basic one from which you can get questions. You can easily answer them if you read and memorize this small area of a basic chapter. Nearly one to five bita will be out from this area where you can score good range marks easily. Not only for exams it’s also important to know about how our complex structure is made up of and what hides inside us. So don’t avoid this basic area.
We came to know the blood groups, how they are classified in nature, and the importance of knowing them. When you are from a biology background it’s more important to know about them. Blood groups are classified based on the presence and absence of antigens and antibodies in the body of living organisms. The four main types of blood groups are A, B, AB, and O.
These are determined by the presences or absences of two antigens on the surface of red blood cells, those two antigens are A and B. These antigens may be proteins, carbohydrates, glycoproteins or glycolipids depending on the blood group system of the living organism. Blood types are inherited and show a contribution from both parents. This is the brief about the article in which we discussed blood groups and their classification.
