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.

Matching Quote

"Oh, the holiness of always being the injured party. The historically oppressed can find not only sanctity but safety in the state of victimization. When access to a better life has been denied often enough, and successfully enough, one can use the rejection as an excuse to cease all efforts. After all, one reckons, "they" don't want me, "they" accept their own mediocrity and refuse my best, "they" don't deserve me."

-Maya Angelou
