MICROANATOMY

Detailed explanation-1: -Receiving blood from the wrong ABO group can be life-threatening. For example, if someone with group B blood is given group A blood, their anti-A antibodies will attack the group A cells. This is why group A blood must never be given to someone who has group B blood and vice versa.

Detailed explanation-2: -It’s the universal donor. Group AB can donate to other AB’s but can receive from all others. Group B can donate red blood cells to B’s and AB’s.

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: -Group AB individuals have neither anti-A nor anti-B antibodies in their plasma. Group AB plasma can therefore be given to patients of any ABO blood group and is often referred to as the universal plasma donor.

Detailed explanation-5: -Only people with blood group AB are most sensitive to infectious diseases which agents carry antigens A, B or both A and B on their cells, since blood of such people does not contain the corresponding natural antibodies.
