If thymus gland of an infant is removed which of the following will not form

Options

A. Monocytes
B. Eosinophils
C. B-lymphocytes
D. T-lymphocytes

Answer

**Step-by-Step Solution:**

1. **Understand the Role of the Thymus Gland:**
The thymus gland is an essential organ located in the chest, near the heart. Its primary function is to facilitate the maturation of T lymphocytes (T cells), which are crucial for the adaptive immune response.

2. **Identify the Origin of Lymphocytes:**
Lymphocytes, including T cells and B cells, originate from stem cells in the bone marrow. However, they undergo different maturation processes:
- **B lymphocytes (B cells)** mature in the bone marrow.
- **T lymphocytes (T cells)** mature in the thymus gland.

3. **Analyze the Impact of Thymus Removal:**
If the thymus gland is removed in an infant, the maturation process for T lymphocytes will be disrupted. Since T cells require the thymus for their development, their formation will be significantly affected.

4. **Evaluate the Options:**
The options provided are:
- Monocytes
- Eosinophils
- B lymphocytes
- T lymphocytes

Among these, T lymphocytes are directly dependent on the thymus for their maturation.

5. **Conclude the Answer:**
Therefore, if the thymus gland is removed, T lymphocytes will not be able to mature and form. The correct answer is **T lymphocytes**.
