Heidi arrived home after a long walk with her dog and found that her mom had dinner ready. Why do you think she is not very hungry?
What will be an ideal response?
Heidi triggered the sympathetic nervous system to be dominant during exercise (walking her dog). The digestive system is dominated by the parasympathetic nervous system. Heidi needs to rest for a while in order for the parasympathetic nervous system to dominate, allowing her to feel hungry.
