A few words of thanks would be greatly appreciated.

Graft - Definition


In medical parlance, a graft is the transplant of a foreign organ into the body of another person, performed because they are lacking a vital organ, or because their organ needs to be healed to start functioning properly, such as is the case with kidney transplants for patients on dialysis. There are two types of grafts, or transplants: autotransplantation, where the graft comes from the same patient; and allotransplantation, where it comes from a donor. Grafts can be removed from living organisms (kidneys, bone fragment, skin, and so on) or after death (heart, lungs, pancreas, cornea, and so on).
