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

Options

A. a) Erythrocytes
B. b) Leucocytes
C. c) Neutrophils
D. d) Thrombocytes

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks for the type of blood cells whose reduction can lead to a clotting disorder and excessive blood loss.

2. **Identify the Types of Blood Cells**: There are three main types of blood cells:
- Erythrocytes (Red Blood Cells - RBC)
- Leukocytes (White Blood Cells - WBC)
- Thrombocytes (Platelets)

3. **Function of Each Blood Cell Type**:
- **Erythrocytes (RBC)**: These cells are primarily responsible for transporting oxygen and carbon dioxide in the blood.
- **Leukocytes (WBC)**: These cells are part of the immune system and help the body fight infections.
- **Thrombocytes (Platelets)**: These cells are crucial for blood clotting. They help in the formation of blood clots to stop bleeding.

4. **Determine the Role in Clotting**: Since the question specifically mentions a "clotting disorder," we need to focus on thrombocytes (platelets). A reduction in the number of platelets can lead to conditions such as thrombocytopenia, which impairs the body's ability to form clots.

5. **Conclusion**: Based on the functions of the blood cells, the correct answer to the question is **Thrombocytes (Platelets)**. Their reduction can indeed cause clotting disorders, leading to excessive loss of blood.

**Final Answer**: Thrombocytes (Platelets)
