Blood Typing Game

In my physiology class yesterday, I learned about blood types and transfusion. It is really interesting how it works.
Anyway I just wanna share something. If you're curious and wanna learn about blood transfusion, I found a site for blood typing game. Here it is http://nobelprize.org/educational_games/medicine/landsteiner/index.html

Make sure you won't kill the patient :) Here is the golden rule of transfusion that I learned from class "Never give a patient a blood transfusion that contains foreign antigens to that patient". For example blood type AB can receive type A, B, AB, O but can only donate to AB. Type AB can receive type O because O is a universal donor.
Have fun!!!!
