Blood Types

Agglutinogens: Antibodies on RBC’s Agglutinins: Antibodies floating in plasma Blood types of A, B, AB, O are determined by the antibodies of the RBC If an RBC has a B antibody then the plasma will have anti-A antibody to react with any unknown RBC Clotting is a danger if the body is exposed to the same unknown RBC twice The first time primes the response and the second triggers the clotting reaction

RH Factors A system based on a different set of RBC’s antibodies There are three different genes for one trait C, D, E If you have a trait DD or Dd you are considered RH+ Clotting also occurs after second exposure to different RH factor
