Percentage of protein is more in
(a) Lymph
(b) Blood
(c) Plasma
(d) W.B.C.

Options

A. Lymph
B. Blood
C. Plasma
D. W.B.C.

Answer

To determine which option has the highest percentage of protein, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Lymph**:
- Lymph is a fluid that circulates throughout the lymphatic system. It is known to have a lower concentration of proteins compared to blood.
- **Conclusion**: Lymph has less protein.

2. **Understanding Blood**:
- Blood consists of two main components: plasma and blood cells (which include red blood cells, white blood cells, and platelets).
- The protein content in blood is primarily found in the plasma, which contains about 6-10% proteins.
- **Conclusion**: Blood has a moderate amount of protein.

3. **Understanding Plasma**:
- Plasma is the liquid component of blood and is composed of about 90% water and around 6-10% proteins.
- While plasma does contain proteins, it is not as concentrated as the total protein content found in blood when considering the blood cells.
- **Conclusion**: Plasma has a lower percentage of protein compared to the total protein in blood.

4. **Understanding White Blood Cells (WBC)**:
- WBCs are primarily involved in the immune response and do not have a high concentration of proteins compared to the total protein content in blood.
- **Conclusion**: WBCs have less protein compared to blood.

5. **Final Comparison**:
- Among lymph, blood, plasma, and WBCs, blood has the highest overall protein content due to the combined presence of proteins in both plasma and blood cells.
- **Final Answer**: The percentage of protein is more in **(b) Blood**.
