Activities of the Digestive System Generally Increase When It Is

Question

Activities of the digestive system generally increase when it is stimulated by
A)sympathetic impulses.
B)parasympathetic impulses.
C)sensory impulses.
D)somatic impulses.

Accepted Answer

The parasympathetic nervous system is responsible for increasing activity in the digestive system. It promotes the secretion of digestive enzymes and increases blood flow to the digestive organs, which leads to increased digestive activity. Sympathetic impulses, on the other hand, have the opposite effect and can inhibit digestive activity. Sensory and somatic impulses may play a role in triggering the digestive system, but they do not directly increase activity in the same way that parasympathetic impulses do.
