1. The division of the NS that will be handling your body's after-dinner activities is the Parasympathetic Nervous System.
Organs involved are the Stomach, Small intestine, Large intestine
Major nerve supply:
- Stomach - Parasympathetic (Vagus)
- Small Intestine - Parasympathetic (Vagus)
- Large Intestine - Parasympathetic (Vagus)
Effects of the nervous system on their functions: The nervous system helps them especially in digestion. Other effects are secretion and absorption.
2. I would explain these effects as the autonomic nervous system responded to the event that transpired. She might have experienced panic attacks or simply palpitation because of the sudden scare that she had after avoiding the bicycle that came out of nowhere. I would say that it was a common reaction as I think if anyone was in the same situation, they would also experience the same effects.
