graft 'graft vt to implant (living tissue) surgically <\grafted a new piece of artery into the ruptured portion of the old artery> vi to perform grafting

graft n

1) the act of grafting

2) something grafted specif living tissue used in grafting

1. n. any organ, tissue, or object used for transplantation to replace a faulty part of the body. A skin graft is a piece of skin cut from a healthy part of the body and used to heal a damaged area of skin. A bone graft is healthy bone collected from the patient or from another person and used to fill a defect in a bone or as a stimulus to fracture healing. A healthy kidney removed from one person and transplanted to another individual is described as a kidney (or renal) graft. Corneal grafts are taken from a recently dead individual to repair corneal opacity (see keratoplasty). Diseased coronary arteries may be replaced by a coronary bypass graft. Artificial grafts are used to replace diseased peripheral arteries and heart valves.

2. vb. to transplant an organ or tissue. See also allograft, xenograft.
