Blood: Types and Transfusions Where it comes from and where it can go
Blood Types • Discovered by Karl Landsteiner in the early 1900s • 4 Types • Blood type established genetically • Receive one allele from each parent • Six possible combinations • These genes cause proteins called Agglutinogens to exist on the surface of all RBCs • In addition, other proteins called Agglutinins • Circulate in the plasma • Ensure only blood cells of your blood type exist in the body
Why is blood type important? Two Special Types of Blood O – The universal donor AB – The universal recipient • Receiving a blood transfusion • Donor’s Agglutinogens must match the receivers • If not, Agglutinins will attack • Causing serious, even fatal, complications
