Lymph nodes form

Options

A. hormones
B. lymph
C. antigens
D. antibodies

Explanation

**Step-by-Step Solution:**

1. **Understanding Lymph Nodes:**
- Lymph nodes are small, bean-shaped structures that are part of the lymphatic system. They play a crucial role in the immune response by filtering lymph fluid and housing immune cells.

2. **Composition of Lymph Nodes:**
- Lymph nodes contain various types of immune cells, including T-cells, B-cells, dendritic cells, and macrophages. These cells are essential for identifying and responding to pathogens.

3. **Role of B-cells:**
- B-cells are a type of lymphocyte that primarily function to produce antibodies. They develop in the bone marrow and migrate to lymph nodes, where they can encounter antigens.

4. **Function of Antibodies:**
- Antibodies are proteins produced by B-cells in response to foreign antigens (such as bacteria, viruses, or tumor cells). They help neutralize or eliminate these pathogens.

5. **Filtering of Antigens:**
- Lymph nodes filter out antigens from the lymph fluid. This process helps the immune system to detect and respond to infections effectively.

6. **Evaluating the Options:**
- The question asks what lymph nodes form. The options provided are:
- Hormones (incorrect)
- Lymph (incorrect)
- Antigens (incorrect)
- Antibodies (correct)

7. **Conclusion:**
- Based on the functions and roles of lymph nodes and B-cells, the correct answer is that lymph nodes form antibodies.

**Final Answer:**
- Lymph nodes form antibodies.
