Blood Type. Our blood is composed of blood cells and an aqueous fluid known as plasma. Human blood type is determined by the presence or absence of certain identifiers on the surface of red blood cells. These identifiers, also called antigens, help the body's immune system to recognize it's own red blood cell type.here are four main ABO blood type groupings: A, B, AB, and O. These blood groups are determined by the antigen on the blood cell surface and the antibodies present in the blood plasma. Antibodies (also called immunoglobulins) are specialized proteins that identify and defend against foreign intruders to the body.
