The operation of transfer of tissue from one site to another.
A method of propagation which involves the uniting of a piece of stem of a desirable plant, the “scion,” to that of a less desirable one, the “stock” or “understock,” to give a stronger root system than the scion would have naturally Many different techniques for grafting have been employed.

Transplanting a portion of skin, bone, or other tissue from one part of the body to another. Grafting is used to replace diseased or injured tissue with healthy tissue from the same body. For example, skin grafts are used to replace skin that has been burned or removed surgically.
The act of applying a graft of skin or tissue from a healthy site to an injured site.
Tissue transplantation involves the transfer of healthy tissue from one part of the body to another (autografting) or from one person to another (allografting). Additionally, tissue transplantation from an animal to a person (xenografting) is also performed.
Grafting is a medical procedure employed to restore or substitute diseased, injured, or impaired tissues or organs. Various common grafting operations include skin grafts, bone grafts, bone marrow transplants, corneal grafts, kidney transplants, heart transplants, liver transplants, heart-lung transplants, heart-valve surgeries, as well as microsurgery on blood vessels and nerves.
In autografting, the transplanted tissue typically integrates well with the surrounding tissue at the new location.
In various other grafting methods, there exists a risk of tissue rejection. However, two exceptions to this risk are grafts between identical twins, as their tissue perfectly matches, and corneal grafting. The cornea lacks a blood supply, which means it has no white blood cells and antibodies to act as a defense system against foreign cells. As a result, corneal grafts have a reduced risk of rejection.
To prevent rejection, medical practitioners strive to find the closest possible match between the recipient’s tissues and the donor’s tissues. The recipient is then administered immunosuppressant drugs to suppress the body’s natural immune response. This helps to ensure a successful tissue or organ transplantation.
