yes, some are listed twice because i guess they're supposed to be put in twice

The surface of red blood cells have carbohydrates markers called "antigens". Those antigens will produce functional proteins called "antibodies" that will fight foreign invaders. Blood type A has the "A antigen" on its surface and will produce "B antibody". Blood type A cannot receive blood from any type with "B antigen" in its name because "B antibody" will see that donation as foreign type. Blood type B has "B antigen" on its surface and will make "A antibody". A person with blood type B can receive blood from types "Blood type B" and "Blood Type O". Blood type AB is the universal "recipient" because it has no blood "antibody". Blood type O is the universal "donor" because it has no blood "antigen"
