A graft from different species is called as:
a. Transplantation is the act of transferring an organ, tissue, or cell from one place to another.
b. Transplants are divided into three categories based on the similarity between the donor and the recipient: autotransplants, allotransplants, and xenotransplants.
c. Autotransplants involve the transfer of tissue or organs from one part of an individual to another part of the same individual.
d. They are the most common type of transplants and include skin grafts, vein grafts for bypasses, bone and cartilage transplants, and nerve transplants.
e. Since the donor and the recipient are the same person and no immunologic disparity exists, no immunosuppression is required.
f. Allotransplants involve transfer from one individual to a different individual of the same species—the most common scenario for most solid organ transplants performed today.
g. Immunosuppression is required for allograft recipients in order to prevent rejection.
h. Finally, xenotransplants involve transfer across species barriers.
