  14. How will the recipient react? • The donor must be a “match” (must not see the antigens on it as foreign) for the recipient otherwise the immune system will reject the new organ • The chance of REJECTION is less when the donor and recipient are closely related or when anti-rejection medication is used.

  15. Why take an immunosuppressant? It will suppress your immune system and reduce the chance of destroying the transplanted organ. What is the risk of suppressing the immune system? It increases the patient’s risk for an infection.
