There are 4 blood types (A, AB, B, and O) excluding the pos or neg aspect, which are all based on the Antigens on the surface of the Red Blood Cells (RBCs). These antigens are what Antiboies detect and bind to and, because antibodies each bind two antigens, they join up all the cells making massive structures that cannot flow through the blood and cause clots. So for example the A antigen will be detected by the anti-A antibody and cause the clott to be forlmed. For this reason we do not have in our systems the antibodies capable of dececting our own antigens, so if you have A antigens (type A blood) you will have only anti-B antibodies and vice versa. If you have both A and B antigens (AB blood) you will have neither anti-A nor ant-B antibodies. If you have no antigens (type O blood) you will have both the anti-A and anti-B antibodies. Recieving donor blood which as antigens to which your own antibodies will be atracted will mean that the blood you receive is clotted up. For exampl is a type A (has anti-B antibodies) receives type B blood (has B antigens) then the antibodies will bind the donor cells. However if a type AB (no antibodies) receives any sort of donor blood it will accept it freely as there are no antibodies tobind any antigens. This is why AB type is known as the Universal Reciever, as it can receive blood from any blood type donor. So if a type O (with both antibodies) receives A type or B type or AB type donor blood then it has antibodies that will bind any of them causing a clot. However O type blood also has no antigens on it RBCs so no matter what antibodies are present the cells will not be bound. This means tha O type donor blood can be put into any resipient without feer the recipients antibodies will bind the cells, and thus O type blood is known as the Universal Donor.
