Gamma -Globulins are synthesised in

Options

A. lymph and lymph nodes
B. liver
C. bone marrow
D. kidney

Answer

**Step-by-Step Solution:**

1. **Understanding Gamma-Globulins**: Gamma-globulins are a type of antibody, which are proteins that play a crucial role in the immune response by identifying and neutralizing pathogens like bacteria and viruses.

2. **Identifying the Site of Synthesis**: The question asks where gamma-globulins are synthesized. We need to analyze the options provided: lymph and lymph nodes, liver, bone marrow, and kidney.

3. **Evaluating Each Option**:
- **Lymph and Lymph Nodes**: This is where gamma-globulins are primarily synthesized. Lymphoid tissues, including lymph nodes, are involved in the production of antibodies by plasma cells.
- **Liver**: While the liver is involved in the production of various proteins, it does not synthesize gamma-globulins specifically. It is more involved in the production of other types of proteins and factors.
- **Bone Marrow**: The bone marrow is responsible for the formation of blood cells, including B cells and T cells, but it is not the primary site for the synthesis of gamma-globulins.
- **Kidney**: The kidneys are primarily involved in filtering blood and do not play a role in the synthesis of gamma-globulins.

4. **Conclusion**: Based on the analysis, the correct answer is that gamma-globulins are synthesized in the **lymph and lymph nodes**.

**Final Answer**: Gamma-globulins are synthesized in lymph and lymph nodes.
