Blood Types

The ABO blood group has 4 blood types which include A,B,AB, and O

Type A- Have an antigen on the surface of red blood cells also have antibody B in their plasma
Type B- Have antigen B on the surface of the red blood cells. If an indiviual with type A blood is given type B blood the antibody B in the recipents blood will combine with the red blood cells of the donor blood due to the fact that those cells have antigen B on the surfaces
Type AB-Indiviuals with type AB blood have both antigen A and antigen B on the surface of their red blood cell they don't have antibody A or B in their plasma. AB blood donors are called universal recipents because most of them can accept all ABO blood types
Type O-Indiviuals with type O don't have antigen A or antigen B on the surface of the red blood cells. people with type O are called universal donors because their blood can be given to most people
