The non-granulatory white blood corpuscles are

Options

A. basophils, eosinophils and neutrophils
B. basophils and monocytes
C. eosinophils and lymphocytes
D. lymphocytes and monocytes

Answer

**Step-by-Step Solution:**

1. **Understanding White Blood Cells (WBCs)**: White blood cells, or leukocytes, are crucial components of the immune system. They are categorized into two main types: granulocytes and agranulocytes.

2. **Defining Granulocytes and Agranulocytes**:
- Granulocytes are WBCs that contain granules in their cytoplasm. They include neutrophils, eosinophils, and basophils.
- Agranulocytes, on the other hand, are WBCs that do not have granules. They include lymphocytes and monocytes.

3. **Identifying Non-Granulatory WBCs**: Since the question specifically asks for non-granulatory white blood corpuscles, we need to focus on the agranulocytes.

4. **Listing Non-Granulatory WBCs**: The non-granulatory white blood corpuscles are:
- Lymphocytes (which include B and T cells)
- Monocytes (which can differentiate into macrophages and dendritic cells)

5. **Conclusion**: Therefore, the non-granulatory white blood corpuscles are lymphocytes and monocytes.

**Final Answer**: The non-granulatory white blood corpuscles are lymphocytes and monocytes.
