The cells involved in inflammatory reactions are

Options

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

Answer

To determine the cells involved in inflammatory reactions, we can follow these steps:

### Step 1: Understand the Types of White Blood Cells (WBCs)
- White blood cells are crucial components of the immune system, and they can be divided into two main categories: granulocytes and agranulocytes.

### Step 2: Identify Granulocytes
- Granulocytes are characterized by the presence of granules in their cytoplasm. The main types of granulocytes include:
- **Neutrophils**: These are phagocytic cells that engulf and digest foreign particles and pathogens.
- **Eosinophils**: These are primarily involved in combating parasitic infections.
- **Basophils**: These cells are involved in allergic reactions and release histamine, which contributes to inflammation.

### Step 3: Identify Agranulocytes
- Agranulocytes do not have granules in their cytoplasm. The main types include:
- **Lymphocytes**: These are involved in the adaptive immune response.
- **Monocytes**: These can differentiate into macrophages and dendritic cells, playing a role in phagocytosis and antigen presentation.

### Step 4: Focus on Inflammatory Reactions
- Inflammatory reactions are characterized by increased blood flow, swelling, and the recruitment of immune cells to the site of injury or infection.
- **Basophils** play a significant role in this process by releasing histamine, which increases blood flow and contributes to inflammation.

### Step 5: Conclusion
- Based on the roles of these cells, the primary cells involved in inflammatory reactions are **basophils**. They release histamine and other mediators that lead to the symptoms of inflammation.

### Final Answer
The cells involved in inflammatory reactions are **basophils**.
