What is the primary role of antigens present on the surface of red blood cells?
What is the primary role of antigens present on the surface of red blood cells?
- To regulate blood pressure.
- To produce antibodies in response to infections.
- To help the immune system identify foreign substances. (correct)
- To transport oxygen throughout the body.
Why is blood group compatibility important in blood transfusions?
Why is blood group compatibility important in blood transfusions?
- To maintain the recipient’s blood glucose levels during the procedure.
- To match the blood viscosity between donor and recipient.
- To ensure the donor's red blood cells are oxygenated properly.
- To prevent the recipient’s immune system from rejecting the donor’s blood. (correct)

Study Notes
- Blood groups are classifications based on the presence or absence of antigens on red blood cells.
- These antigens are proteins that help the immune system recognize and respond to foreign substances.
- Blood group compatibility is crucial in transfusions and organ transplants to prevent rejection by the recipient's immune system.
- Blood type is inherited from parents through genes, with variations determining A and B antigens, and a separate gene for the O blood type.
- The Rh factor, another antigen, determines whether blood is Rh-positive or Rh-negative.
- Blood group is determined by the combination of antigens in red blood cells and the Rh factor status.
- The most common blood groups are A, B, AB, and O, differentiated by the presence or absence of antigens.
ABO Blood Group System
- Group A: A antigens on red blood cells, B antibodies in plasma.
- Group B: B antigens on red blood cells, A antibodies in plasma.
- Group AB: Both A and B antigens on red blood cells, no antibodies in plasma.
- Group O: No A or B antigens on red blood cells, both A and B antibodies in plasma.
