Antigens on the red blood cells determine a person’s blood type.
Antibodies in the blood plasma attack foreign blood that is not compatible with those antigens.

Brief clarification: for example, type A blood has A antigens on the RBCs and anti‑B antibodies in the plasma; type B has B antigens and anti‑A antibodies; type AB has both antigens (no anti‑A or anti‑B antibodies); type O has neither antigen (both anti‑A and anti‑B antibodies). The Rh factor (positive or negative) is a separate antigen that also affects compatibility.
