Definition
Plain language
A piece of tissue transplanted into the body to replace something damaged.
As stated in the literature
Transplanted tissue or engineered construct implanted to restore structure or function; assessed by patency, integration and absence of chronic inflammation.
Also called: grafts
Why it matters: Whether a graft stays open, knits into surrounding tissue and avoids chronic inflammation is what decides if the operation actually helped.
For example, a section of engineered tissue can be sewn in to replace a damaged stretch of airway.
