What are the functions of lymph ?

Options

A. Exchange of nutrients and hormones
B. Absorption of fats
C. Accelerates coagulation of blood
D. Both (a) and (b)

Answer

To answer the question "What are the functions of lymph?", we can break down the functions of lymph into several key points:

### Step-by-Step Solution:

1. **Definition of Lymph**:
- Lymph is a clear fluid that circulates throughout the lymphatic system. It contains white blood cells (WBCs) and is derived from interstitial fluid that bathes the body’s cells.

2. **Moistening Body Cells**:
- One of the primary functions of lymph is to keep body cells moist. This is essential for cellular function and nutrient exchange.

3. **Transport of Nutrients and Hormones**:
- Lymph plays a crucial role in transporting nutrients and hormones. It helps in the distribution of these substances to various parts of the body.

4. **Absorption of Fats**:
- Lymph is involved in the absorption of fats from the digestive system. Specifically, it helps in the transport of fatty acids and fat-soluble vitamins from the intestines to the bloodstream.

5. **Transport of Oxygen**:
- Although lymph primarily does not transport oxygen (this is mainly the function of blood), it does assist in the overall transport of nutrients and metabolic products.

6. **Transport of Antibodies and Lymphocytes**:
- Lymph carries antibodies and lymphocytes, which are crucial for the immune response. This helps the body fight infections and diseases.

7. **Removal of Metabolic Waste**:
- Lymph helps in the removal of metabolic waste products from cells, facilitating their excretion from the body.

8. **Coagulation of Blood**:
- Lymph does not directly accelerate blood coagulation. This function is primarily associated with blood components.

### Conclusion:
Based on the functions discussed, we can conclude that lymph is involved in the exchange of nutrients and hormones, the absorption of fats, and the transport of immune cells. Therefore, the correct answer to the question is that both A (exchanges nutrients and hormones) and B (absorbs fats) are correct.

### Final Answer:
**D: Both A and B are correct.**
