Quizplus · Accepted Answer

This is correct. The parasympathetic nervous system is responsible for stimulating digestive activity, while the sympathetic nervous system inhibits digestive activity in favor of other bodily functions such as the "fight or flight" response. Therefore, parasympathetic impulses would increase the movement of chyme through the small intestine, while sympathetic impulses would inhibit it.
