- **Agranulocytes**: These cells do not have granules in their cytoplasm.

3. **Subtypes of WBCs**:
- **Granulocytes** include:
- Neutrophils
- Eosinophils
- Basophils
- **Agranulocytes** include:
- Lymphocytes
- Monocytes

4. **Percentage Composition of WBCs**: The distribution of different types of WBCs in the blood is as follows:
- Neutrophils: 65-75%
- Lymphocytes: 20-25%
- Monocytes: 10-15%
- Eosinophils: 5-10%
- Basophils: Less than 1%

5. **Identifying the Most Abundant WBC**: Based on the percentage composition, neutrophils have the highest percentage among the WBCs, making them the most abundant type of white blood cells in the body.

6. **Conclusion**: Therefore, the most abundant WBCs are neutrophils.
