Natural anticogulant in human body is secreted by :-

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding Anticoagulants**: Anticoagulants are substances that prevent blood clotting. The body has natural anticoagulants that help regulate blood flow and prevent excessive clotting.

2. **Identifying the Natural Anticoagulant**: The main natural anticoagulant in the human body is heparin. It plays a crucial role in preventing blood clots.

3. **Source of Heparin**: Heparin is secreted by specific cells in the body. The question asks which type of cells secrete this natural anticoagulant.

4. **Evaluating the Options**:
- **Lymphocytes**: These are white blood cells involved in the immune response but do not secrete heparin.
- **Neutrophils**: These are also white blood cells that play a role in fighting infections but are not responsible for heparin secretion.
- **Monocytes**: These are another type of white blood cell that differentiates into macrophages and dendritic cells, but they do not secrete heparin.
- **Basophils**: These are a type of white blood cell that, along with mast cells, is known to secrete heparin.

5. **Conclusion**: Based on the information, heparin, the natural anticoagulant, is secreted by basophils and mast cells. Therefore, the correct answer to the question is **basophils**.

**Final Answer**: Basophils
