Blood Groups and Transfusions: After mixed success with transfusions, scientists determined that blood was of different types and only certain combinations were compatible. Clumping of red blood cells following transfusion is called agglutination . This clumping is due to the interaction of proteins on the surfaces of red blood cells called antigens with certain proteins called antibodies carried in the plasma. Blood Types: Define antigen and antibody- antigen- A substance or part of a substance (living or nonliving) that is recognized as a foreign by the immune system, activates the immune system, and reacts with the immune cells or their products. antibody- A protein molecule that is released by a plasma cell (a daughter cell of an activated B lymphocyte) and that binds specifically to an antigen, and immunoglobulin.
