MICROANATOMY

Detailed explanation-1: -The reaction between red cells and corresponding antibodies usually results in clumping-agglutination-of the red cells; therefore, antigens on the surfaces of these red cells are often referred to as agglutinogens.

Detailed explanation-2: -Antibodies and antigens Antibodies are proteins found in plasma. They’re part of your body’s natural defences. They recognise foreign substances, such as germs, and alert your immune system, which destroys them. Antigens are protein molecules found on the surface of red blood cells.

Detailed explanation-3: -Your immune system reacts to foreign red blood cells when they have markers, called antigens, that are unlike the antigens on your own cells. The unfamiliar antigens trigger your immune system to make RBC antibodies to destroy the foreign red blood cells.
