Exam 2 Review:  Chapter 5:  Skin Grafts

skin graft  - A surgical graft of healthy skin (primarily epidermis) from one part of the body to another or from one individual to another in order to replace damaged or lost skin.

autograft - A tissue or organ grafted into a new position in or on the body of the same individual; the most desirable source for skin grafting in burns, if possible, because no rejection will occur.

isograft - A graft of tissue that is obtained from a donor genetically identical to the recipient for which no rejection will occur.

allograft = homograft - A tissue or organ transplanted from a donor of the same species but different genetic makeup; the recipient's immune system must be suppressed to prevent rejection of the graft. 

xenograft = heterograft - A type of tissue graft in which the donor and recipient are of different species; most often restrictred to temporary grafting (as in cases of severe burns) because the recipient's immune system must be suppressed to prevent rejection of the graft.
