The most abundent type of WBCs (granulocytes)
in humen blood are

Options

A. Basophils
B. Neutrophils
C. Monocytes
D. Eosinophils

Answer

To answer the question regarding the most abundant type of WBCs (granulocytes) in human blood, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of White Blood Cells (WBCs)**:
- White blood cells are divided into two main categories: granulocytes and agranulocytes.
- Granulocytes contain granules in their cytoplasm, while agranulocytes do not.

2. **Identify the Types of Granulocytes**:
- Granulocytes are further classified into three types:
- Neutrophils
- Eosinophils
- Basophils

3. **Know the Percentages of Each Type**:
- Neutrophils: Approximately 75%
- Eosinophils: Approximately 5-10%
- Basophils: Approximately 1-2%

4. **Determine the Most Abundant Granulocyte**:
- Among the granulocytes, neutrophils have the highest percentage in the blood, making them the most abundant type of WBCs.

5. **Conclude the Answer**:
- Therefore, the most abundant type of WBCs (granulocytes) in human blood are **neutrophils**.
