प्रश्न
Why do doctors have to carry many tests for selecting a person to be a suitable donor for someone who is going for an organ transplant and not take the organ from just any body? Explain giving reason.
उत्तर
Because it is grafted and would be rejected sooner or later. Tissue matching and blood group matching are essential before undertaking any graft/transplant and even after this, the patient has to take immune suppressants all his/her life. The body is able to differentiate ‘self’ and ‘nonself’ and the cell-mediated immune response is responsible for graft rejection.
