Question

What is the physiological basis of blood grouping?

Answer 1

ABO blood group system,the classification of human blood based on the presence or abscence of the antigens A and B which are carried on the surface of the red cells

Answer 2

Answer:

ABO blood group in human beings is discussed below.

Explanation:

• The ABO blood group system divides all people into one of eight blood types based on the inherited characteristics of red blood cells (erythrocytes), which are identified by the presence or absence of antigens A and B that are carried on their surface. As a result, individuals may have type A, type B, type O, or type AB blood.
• Serum (fluid) antibodies against type B red cells are present in blood that contains red cells with type A antigen on their surfaces.
• When type B blood is transfused into people with type A blood, the recipient's blood's antibodies will kill the injected blood's red blood cells.
• Anti-A antibodies in type B blood will similarly damage type A red blood cells. Unless there is incompatibility with another blood group system, type O blood can be injected into people with type A, B, or O blood. Blood of types A, B, or O can be given to people with type AB blood.
