why is blood type important ?
Answers
Answer:
Everyone's blood contains the same basic stuff, but mixed in with that stuff are "antigens." These special proteins act like an ID tag for a person's blood, letting his or her body know the hlond is the person's own and not a foreign invader. Antigen combinations make different blood types-eight in all-which are passed along from parent to child just like eye color and other genetic traits if you get in an accident and lose a lot of blood (or get sick and need a fresh supply), you'll have to go to the hospital to get a "transfusion" of someone else's red stuff. Transfusions are simple proce- dures-and the most common type of hospital procedure-but they always start with the doctor determining the patient's blood type. If you get a transfusion of the wrong type, your immune system will think it's an infection and go on the attack.
