The replacement of lost or damaged bodily tissue with an allograft or surgical substitute of a body part from one individual to a different person: An allotransplantation includes cornea (transparent front of the eye), cartilage (rubber-like padding that covers and protects the ends of long bones at the joints), bone, arteries (vessels that carry blood away from the heart), and cadaver (dead-body) epidermis that is stored in a skin-tissue bank.

Allotransplantation involves the moving of a part from one individual into another one which are usually not related to each other.
