MICROANATOMY

Detailed explanation-1: -blood group B – has B antigens with anti-A antibodies in the plasma. blood group O – has no antigens, but both anti-A and anti-B antibodies in the plasma. blood group AB – has both A and B antigens, but no antibodies.

Detailed explanation-2: -A+ blood has anti-B antibodies, so that patient can’t receive any blood who has B antigen. AB+ blood has A antigen and B antigen. Thus the recipient’s anti-B antibodies can bind to the B antigen from the donor and may cause massive immune response leading to kidney failure, clot formation and death.

Detailed explanation-3: -Anti-A and anti-B are found in the sera of individuals who lack the corresponding antigens. They are produced in response to environmental stimulants, such as bacteria. These antibodies are produced after birth, reaching a peak at 5–10 years of age, and declining with increasing age.

Detailed explanation-4: -Anti-B antibody would attack blood cells that contain B antigen. Group B: The surface of the red blood cells contains B antigen, and the plasma has anti-A antibody. Anti-A antibody would attack blood cells that contain A antigen.

Detailed explanation-5: -When a mother-to-be and father-to-be are not both positive or negative for Rh factor, it’s called Rh incompatibility. For example: If a woman who is Rh negative and a man who is Rh positive conceive a baby, the fetus may have Rh-positive blood, inherited from the father.
