Which of the following statement is true for Lymph

Options

A. WBC and serum
B. All components of blood except RBCs and some proteins
C. RBCs, WBCs and Plasma
D. RBCs, Proteins and Platelets

Answer

To determine which statement is true for lymph, let's analyze the characteristics of lymph step by step.

### Step-by-Step Solution:

1. **Understanding Lymph**: Lymph is a clear to milky fluid that is part of the lymphatic system. It is derived from interstitial fluid, which is the fluid that surrounds the cells in tissues.

**Hint**: Remember that lymph is formed from interstitial fluid, which is the fluid that exists between cells.

2. **Composition of Lymph**: Lymph primarily contains white blood cells (WBCs), proteins, and other substances. However, it does not contain red blood cells (RBCs) and has fewer proteins compared to blood plasma.

**Hint**: Focus on the components that are present in lymph and those that are absent. Lymph lacks RBCs.

3. **Key Differences from Blood**:
- Blood contains RBCs, WBCs, platelets, and plasma (which includes clotting factors).
- Lymph contains WBCs but lacks RBCs and has a different protein composition than blood plasma.

**Hint**: Consider the main components of blood and how lymph differs from it.

4. **Appearance of Lymph**: Lymph can appear milky due to the presence of lipids, especially after a meal. This is important to note as it distinguishes lymph from other fluids.

**Hint**: Recall that the milky appearance of lymph is due to lipid content.

5. **Conclusion**: Based on the above points, the correct statement about lymph is that it contains all components of blood except for RBCs and some proteins.

**Hint**: Look for the statement that emphasizes the absence of RBCs and the presence of WBCs and some proteins.

### Final Answer:
The true statement for lymph is: "It contains all components of blood except RBCs and some proteins."
