Name the agranulocytes responsible for immune response of the body

Options

A. basophils
B. neutrophils
C. eosinophils
D. lymphocytes

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the name of the agranulocytes that are responsible for the immune response in the body. Agranulocytes are a type of white blood cell (WBC) that do not have granules in their cytoplasm.

2. **Differentiating White Blood Cells**: White blood cells are categorized into two main types: granulocytes and agranulocytes. Granulocytes have a lobed nucleus and contain granules, while agranulocytes do not have these features.

3. **Identifying Agranulocytes**: The two main types of agranulocytes are lymphocytes and monocytes. However, the question specifically asks about the agranulocytes responsible for the immune response.

4. **Focusing on Lymphocytes**: Among the agranulocytes, lymphocytes play a crucial role in the immune response. There are two primary types of lymphocytes:
- **B Lymphocytes (B Cells)**: These are responsible for humoral immunity, which involves the production of antibodies.
- **T Lymphocytes (T Cells)**: These are involved in cell-mediated immunity, which does not involve antibodies but rather the direct killing of infected cells.

5. **Conclusion**: Therefore, the agranulocytes responsible for the immune response of the body are **T lymphocytes and B lymphocytes**.

### Final Answer:
The agranulocytes responsible for the immune response of the body are **T lymphocytes and B lymphocytes**.
