Detailed explanation-1: -Your blood type is based on whether or not certain proteins are on your red blood cells. These proteins are called antigens. Your blood type (or blood group) depends on what types your parents passed down to you. Blood is often grouped according to the ABO blood typing system.

Detailed explanation-2: -Blood group antigens are either sugars or proteins, and they are attached to various components in the red blood cell membrane. For example, the antigens of the ABO blood group are sugars. They are produced by a series of reactions in which enzymes catalyze the transfer of sugar units.

Detailed explanation-3: -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-4: -The 2 major classifications of blood are the ABO system and the Rh system. The 4 blood groups are A, B, AB and O. Each of these will be either Rh-positive or Rh-negative.

Detailed explanation-5: -Serology : Serology is the study of interaction between an antigen and an antibody.
