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 O 2 to cells; remove CO 2 O 2 binds to hemoglobin proteins Dead cells filtered by liver & spleen

NormalSickle Cell

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 ABO Blood Groups

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