LET’S SUMMARIZE!

  • When an antigen and antibody match & bind this leads to blood clotting (very dangerous!)
  • The different blood types have different antigens on their red blood cells and different antibodies in their blood plasma.
  • During a blood transfusion it is very important to pay attention to the blood types.
