Name the blood cells, whose reduction in number can cause clotting disorder, leading to excessive loss of blood from the body.

Options

A. Erythrocytes
B. Leucocytes
C. Neutrophils
D. Thrombocytes

Answer

**Step-by-Step Solution:**

1. **Understanding Blood Cells**: Blood is composed of various types of cells, primarily red blood cells (RBCs), white blood cells (WBCs), and platelets (thrombocytes). Each type of blood cell has a specific function.

2. **Identifying the Role of Blood Cells**:
- **Erythrocytes (RBCs)**: These are responsible for transporting oxygen throughout the body due to the presence of hemoglobin. They do not play a role in blood clotting.
- **Leukocytes (WBCs)**: These are involved in the immune response and help fight infections. They also do not contribute to the clotting process.
- **Thrombocytes (Platelets)**: These are crucial for blood clotting. They help form clots at the site of a wound to prevent excessive blood loss.

3. **Recognizing Clotting Disorders**: A reduction in the number of thrombocytes (platelets) can lead to clotting disorders. This means that if there are not enough platelets, the body cannot effectively stop bleeding.

4. **Conclusion**: The blood cells whose reduction in number can cause a clotting disorder, leading to excessive loss of blood from the body, are the **thrombocytes** (platelets).

**Final Answer**: Thrombocytes (Platelets)
