MICROANATOMY

Detailed explanation-1: -Group B can donate red blood cells to B’s and AB’s. Group A can donate red blood cells to A’s and AB’s. Group O can donate red blood cells to anybody.

Detailed explanation-2: -B type blood has anti-A antibody in the plasma. AB has neither A nor B antibody in the plasma.

Detailed explanation-3: -People with type AB+ blood are universal recipients because they have no antibodies to A, B or Rh in their blood and can receive red blood cells from a donor of any blood type. Plasma transfusions are matched to avoid A and B antibodies in the transfused plasma that will attack the recipient’s red blood cells.

Detailed explanation-4: -B positive red blood cells can be given to both B positive and AB positive patients. B positive patients can receive blood from B positive, B negative, O positive and O negative donors.

Detailed explanation-5: -AB+ blood has both A and B antigens at the surface of the red blood cells, while other blood groups (A and B) only have one, or lack them altogether (group O). Because of this unique combination, AB+ donors’ blood can only be given to others with AB+ blood.
