Question

Give scientific reason.

Person who has undergone a heart transplant needs lifetime supply of immunosuppressants.

Answer 1

1. Immunosuppressants are the drugs that reduce the level of immune activity and the risk of rejection of foreign bodies such as transplant organs.
2. After transplantation, there is a risk of graft rejection as the body may recognize the transplanted organ/tissue as foreign and may trigger an immune response thereby damaging the transplanted organ. Therefore, the heart recipient has to rely upon lifetime supply of immunosuppressants.
