Which destroy antigens?

Explanation

To answer the question "Which destroys antigens?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Antigens**:
- Antigens are molecules that can provoke an immune response. They can be found either inside or outside the body and are typically foreign substances like bacteria, viruses, or toxins.

2. **Role of Antibodies**:
- Antibodies are specialized proteins produced by the immune system in response to antigens. Their primary function is to identify and neutralize these foreign invaders.

3. **Mechanism of Action**:
- Once antibodies bind to antigens, they mark them for destruction. This process can involve various immune cells, including macrophages, which engulf and digest the antibody-antigen complexes.

4. **Additional Immune Response**:
- In addition to antibodies, certain white blood cells (like macrophages) produce chemicals known as antitoxins that help in neutralizing toxins associated with antigens.

5. **Conclusion**:
- Therefore, the primary agents that destroy antigens are antibodies.

### Final Answer:
Antibodies destroy antigens.
