A. Peristalsis
B. Digestion
C. Excretion
D. Memory and learning

Answer

**Step-by-Step Solution:**

1. **Understanding the Autonomic Nervous System (ANS):**
- The ANS is a part of the peripheral nervous system that controls involuntary bodily functions. It regulates processes such as heart rate, blood pressure, digestion, and respiratory rate.

2. **Identifying Functions of the ANS:**
- The ANS is responsible for controlling:
- Blood pressure
- Heart rate
- Breathing rate
- Body temperature
- Digestion and metabolism
- Production of fluids (like saliva, sweat, and tears)
- Urination
- Peristalsis (the wave-like muscle contractions in the digestive tract)

3. **Identifying Functions Not Related to the ANS:**
- The question asks for an activity that is not related to the ANS.
- Memory and learning are cognitive functions primarily associated with the brain, specifically the hippocampus, which is not controlled by the ANS.

4. **Conclusion:**
- Among the options provided, the function that is not related to the autonomic nervous system is **memory and learning**.

5. **Final Answer:**
- The correct answer is **option D: memory and learning**.
