Individuals have red blood cells with the A antigen on their surface, and blood serum containing antibodies against the B antigen. Therefore, a group A person can only receive blood from people in groups A or O (with A being preferable).
Individuals have red blood cells with the B antigen on their surface, and blood serum containing antibodies against the A antigen. Therefore, a group B person can only receive blood from people in groups B or O (preferably B).
Individuals have red blood cells with both A and B surface antigens, and their blood serum does not contain antibodies against either A or B antigen. Therefore, a person with type AB blood can receive blood from any group (preferably AB) but cannot donate blood except to another AB.
Individuals have red blood cells with neither A or B surface antigen, but their blood serum contains antibodies against both A and B antigens. Therefore, a group O person can only receive blood from group O.
