Tissue transplanted from one part of an individual's body to another part is called a(n) _____________.

• A. Allograft
• B. Autograft
• C. Xenograft
• D. Composite graft

Answer: (B)

Tissue that is transplanted from one part of an individual’s body to another part is referred to as an autograft. This type of graft utilizes the patient’s own tissue, minimizing the risk of rejection since the immune system recognizes it as self. For example, a skin graft taken from one area of a person's body to repair another area is a classic use of an autograft.

Other types of grafts, such as allografts, involve tissue from a donor of the same species but not the same individual, thereby introducing potential for immune rejection. Xenografts come from different species and also face significant compatibility issues. Composite grafts consist of different types of tissues, which may also include both autogenous and non-autogenous elements, depending on the context. In contrast, the autograft is straightforward and efficient, particularly advantageous in medical procedures requiring repair or reconstruction.
