rejection definition


A process in which the immune system of a body attacks an organ or tissue, either its own or tissue transplanted into it from another organism. (See xenotransplantation.)

Note: Rejection is the most serious problem faced in surgery involving organ transplants. Drugs are used to suppress the immune system after organ transplant in order to prevent the rejection of and eventual death of the transplanted tissue.
