One function of the immune system is to attack the foreign cells to protect the body. In organ transplants, the body recognizes that the new organ is made of foreign cells. What kind of medicine would you give a patient to increase the chances of transplant success?
Answer
A
Medicine that allows the immune system to produce and secrete hormones.
B
Medicine that makes the immune system less effective.
C
Medicine that makes the immune system more effective.
D
Medicine that allows the immune system to regulate nerve responses.
Explanation
The immune system may attack a transplanted organ because it recognizes the organ’s cells as foreign. Medicine that makes the immune system less effective can reduce this attack and increase the chance that the transplant succeeds. This is the purpose of immunosuppressant medicine, so the correct choice is “Medicine that makes the immune system less effective.”
