What is the source of antibidies of blood groups abd how are they already present in blood |
|
Answer» Answer: Blood group AB is the least common, and these INDIVIDUALS will have neither anti-A nor anti-B in their serum. ABO ANTIBODIES in the serum are formed naturally. Their PRODUCTION is stimulated when the immune SYSTEM encounters the "missing" ABO blood group antigens in foods or in micro-organisms. |
