A "donor site" refers to the specific area of the body where tissue or organs are harvested for transplantation. This can include skin, bone, or organs like the kidney or liver. The choice of donor site depends on the type of transplant needed and the health of the donor. In medical procedures, the donor site is carefully selected to minimize complications and ensure the best possible outcome for the recipient. After harvesting, the donor site may require care and monitoring to promote healing and reduce the risk of infection.
