The ABO blood group system is based on the presence or absence of two antigens, A and B, on the surface of red blood cells.
Type A individuals have A antigens, and type B individuals have B antigens.
Glycoproteins on the cell membrane determine blood compatibility, and a person with type A blood has antibodies against type B antigens, preventing them from accepting type B blood without a transfusion reaction.
