Rejection
Rejection
Rejection (/rɪˈdʒɛkʃən/) is a term used in various fields of medicine to describe the body's refusal to accept a foreign object or substance. It is most commonly associated with transplantation medicine, where the recipient's immune system attacks the transplanted organ or tissue.
Etymology
The term "rejection" comes from the Latin reicere, which means "to throw back". In the medical context, it refers to the body's defensive response to throw back or reject foreign substances.
