Detailed explanation-1: -blood group A – has A antigens on the red blood cells with anti-B antibodies in the plasma. blood group B – has B antigens with anti-A antibodies in the plasma. blood group O – has no antigens, but both anti-A and anti-B antibodies in the plasma.
Detailed explanation-2: -A type blood has only A antigens on red blood cells. B type blood has only B antigens on red blood cells. AB has both A and B antigens on red blood cells. O has neither A nor B antigens on red blood cells.
Detailed explanation-3: -The liquid part of your blood without cells (serum) is mixed with blood that is known to be type A and type B. People with type A blood have anti-B antibodies. People with type B blood have anti-A antibodies. Type O blood contains both types of antibodies.
Detailed explanation-4: -At present, 33 blood group systems representing over 300 antigens are listed by the International Society of Blood Transfusion.
Detailed explanation-5: -The immune system forms antibodies against whichever ABO blood group antigens are not found on the individual’s RBCs. Thus, a group A individual will have anti-B antibodies and a group B individual will have anti-A antibodies.
