Question

The principle obstacle standing in the way of large scale successful transplantation of organs in man is

• A. Immunological reaction of foreign bodies
• B. Religious and ethical considerations
• C. Lack of effective surgical techniques
• D. Sufficient availability of organs from donors

Answer 1

The correct option is A Immunological reaction of foreign bodies

The principle obstacle standing in the way of large-scale successful transplantation of organs is the immunological reactions of foreign bodies. Almost everyone who receives an organ transplant has to take immunosuppressant drugs. The body recognizes a transplanted organ as a foreign mass. This triggers a response by the body's immune system to attack it. By weakening the immune system, immunosuppressant drugs decrease the body's reaction to the foreign organ. The drugs allow the transplanted organ to remain healthy and free from damage.
