Final answer:
An autograft is a type of graft that comes from a person's own body, which is employed to replace or repair damaged tissues, with a reduced risk of immune rejection.
Step-by-step explanation:
The type of graft that comes from a person's own body is known as an autograft. Autografting involves the transplantation of tissue, such as skin, bone, or blood vessels, from one area of an individual's body to another area. This technique is often used to treat burns, replace damaged blood vessels, or repair other tissues. Since the transplanted tissue comes from the same individual, the risk of immune rejection is significantly reduced compared to other types of grafts like allografts (from another human) or xenografts (from an animal). Moreover, advancements in the field are leading towards the development of in vitro organ growth from an individual’s own cells, which would further eliminate the risk of rejection.
