Peyer's patches produce

Options

A. mucous
B. lymphocytes
C. trypsin
D. lysozyme

Answer

**Step-by-Step Solution:**

1. **Understanding Peyer's Patches**:
- Peyer's patches are small organs located in the small intestine. They are part of the lymphatic system and play a crucial role in the immune response.

2. **Identifying the Type of Organ**:
- Peyer's patches are classified as secondary lymphoid organs. This means they are involved in the immune response, particularly in the interaction between antigens and antibodies.

3. **Function of Secondary Lymphoid Organs**:
- Secondary lymphoid organs, including Peyer's patches, are primarily sites for the lodging of lymphocytes and for antigen-antibody interactions. They do not produce lymphocytes but provide an environment for their activation and proliferation.

4. **Differentiating Between Primary and Secondary Lymphoid Organs**:
- Primary lymphoid organs (like bone marrow and thymus) are responsible for the production, development, and maturation of lymphocytes. In contrast, secondary lymphoid organs (like Peyer's patches) serve as sites for the interaction of lymphocytes with antigens.

5. **Identifying the Correct Answer**:
- Among the options given (mucus, lymphocytes, trypsin, and lysozyme), the correct answer is lymphocytes. Peyer's patches are involved in the lodging and activation of lymphocytes, which are crucial for the immune response.

**Final Answer**: Peyer's patches produce lymphocytes.
