There are four different blood types. A, B, AB, and O. Type A blood has A antigens and anti B antibodies. Type B blood has B antigens and anti A antibodies. Type AB has both A and B antigens and neither antibodies. Lastly, type O blood has no antigens but both anti A and B antibodies. When corresponding antigns/anti-antibodies mix, the result is agglutination which eventually leads to blood clots and heart attacks or strokes. For example, type A and B can't mix because type A has A antigens and anti B antibodies and type B blood has the opposite so it will result in agglutination. Type O is a universal donor becuase it has no antigens and type AB is a universal recipient becuase it has no antibodies.
