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: -The ABO System The presence or absence of A or B antigens gives us four main blood types: A type blood has only A antigens on red blood cells. B type blood has only B antigens on red blood cells. AB has both A and B antigens on red blood cells.
Detailed explanation-3: -In the AB blood group, both the antigens A and B are present on the red cells of the individual, and the serum contains neither anti-A nor anti-B antibodies.
Detailed explanation-4: -It was not until the year 1900, when Karl Landsteiner at the University of Vienna, discovered why some blood transfusions were successful while others could be deadly. Landsteiner discovered the ABO blood group system by mixing the red cells and serum of each of his staff.
