What antigens and antibodies determine blood type?

There are four major blood types determined by presence or absence of two antigens - A and B - on the surface of red blood cells, as well as antibodies A and  B  found in blood plasma.

Blood type A - red cells have A antigen and  B antibody in plasma

Blood type B - red cells have antigen B and antibody A in plasma.

Blood type AB  - red cells have both A and B antigens but no antibody in plasma.

Blood type O - red cells have no antigen  but there are both antibody A and B in plasma.
