Question

A person without thymus would not be able to

• A. Reject a tissue transplant
• B. Receive a tissue transplant
• C. Develop an inflammatory response
• D. Produce antibodies

Answer 1

Answer: (A)

Reject a tissue transplant

The thymus is a specialized primary lymphoid organ of the immune system. Within the thymus, T cells mature. T cells are critical to the adaptive immune system, where the body adapts specifically to foreign invaders. The thymus is the largest and most active during the neonatal and pre-adolescent periods. Removal of the thymus results in immunodeficiency because T- cells do not undergo maturation and this results in suppression of the immune system. Hence, a person without thymus would not be able to reject a tissue transplant because T cells are suppressed.

So, the correct answer is 'Reject a tissue transplant'.
