Question

Quizplus · Accepted Answer

The main reason for the rejection of transplanted tissue is caused by the immune response by the host's body, where cytotoxic T cells and antibodies will recognize the foreign tissue as non-self and destroy it. This is known as acute rejection. In some cases, helper T cells and antibodies can also contribute to the rejection of the transplanted tissue. The host body's antigens do not prevent the attachment of the transplanted tissue, but rather it is the recognition of foreign antigens on the transplanted tissue that triggers the immune response. The rerouting of blood supply or the inability of red blood cells to carry oxygen is not a primary cause of rejection in tissue transplants.
