What is the definition or description of: skin graft?

Skin coverage graft: A skin graft is surgically placed piece of skin that is used to cover a wound. It can be a full thickness piece of skin, or a split thickness skin graft, meaning not all layers of the dermis are included. They each have different characteristics, and may be used on different parts of the body. Skin grafts are often used for treatment of burns, traumatic injuries, or reconstruction.

Patch work: A skin graft involves taking skin from one area of the body and transplanting it to another part, usually to help cover or close a wound. The graft can be full thickness, using all layers of the skin, or it can be split-thickness, which is just part of the superficial epidermal layer.
