Platelets Form clots when bleeding Proteins form a web to trap cells & platelets

White Blood Cells Remove foreign invaders & dead cells Able to move through body tissue

Red Blood Cells Produced from stem cells in bone marrow Lose nucleus as they mature Transport O2 to cells; remove CO2 O2 binds to hemoglobin proteins Dead cells filtered by liver & spleen

Sickle Cell Normal

ABO Blood Groups Proteins on blood cells (antigens) determine blood type Antigens: proteins on cells that identify cells as foreign or natural on the surface of RBCs Antibodies: proteins from WBCs to attack invaders in the blood plasma

Group A blood A antigens on the surface of your RBCs B antibodies in your blood plasma

Group B blood B antigens on the surface of your RBCs A antibodies in your blood plasma

Group AB blood A and B antigens on the surface of your RBCs no A or B antibodies at all in your blood plasma

Group O blood No A or B antigens on the surface of your RBCs both A and B antibodies in your blood plasma

If you have type A blood, can you receive: Type B blood from a donor? Type AB blood from a donor? Type O blood from a donor?

If you have type B blood, can you receive: Type A blood from a donor? Type AB blood from a donor? Type O blood from a donor?

If you have type AB blood, can you receive: Type A blood from a donor? Type B blood from a donor? Type O blood from a donor?

If you have type O blood, can you receive: Type A blood from a donor? Type B blood from a donor? Type AB blood from a donor?

Rh Factors Rh+ Rh- Protein found in blood Can receive Rh+ or Rh- blood Lack protein in blood Only receive Rh- blood
