Explanation:
Detailed explanation-1: -The immune system White blood cells normally attacks foreign tissue, including transplants. This reaction is called rejection . Rejection is triggered when the immune system recognizes certain molecules on the surface of a cell as foreign. These cell-surface molecules are called antigens.
Detailed explanation-2: -When a patient receives an organ transplant, the immune system often identifies the donor organ as “foreign” and targets it with T cells and antibodies made by B cells. Over time, these T cells and antibodies damage the organ, and may cause reduced organ function or organ failure.
Detailed explanation-3: -(ii) The cell-mediated immune response is responsible for the graft rejection.
