A person without thymus would not be able to

Options

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

Answer

**Step-by-Step Solution:**

1. **Identify the Role of the Thymus Gland:**
- The thymus gland is a lobular structure located on the dorsal side of the heart and aorta. It plays a crucial role in the development of the immune system.

2. **Understand the Function of T-Lymphocytes:**
- The thymus contains lymphoid tissue, which is responsible for the maturation and proliferation of T-lymphocytes (T-cells). T-lymphocytes are essential components of the adaptive immune response.

3. **Consequences of Thymus Absence:**
- In a person without a thymus, the development of T-lymphocytes is severely impaired. As a result, the immune system cannot effectively distinguish between self and non-self cells.

4. **Implications for Transplantation:**
- T-lymphocytes are crucial for recognizing foreign tissues (non-self) during transplantation. Without a functional thymus, the person would not be able to mount an immune response to reject transplanted tissues.

5. **Conclusion:**
- Therefore, a person without a thymus would not be able to reject tissue transplants, as their immune system lacks the necessary T-lymphocytes to perform this function.

**Final Answer:**
A person without thymus would not be able to reject tissue transplants.
