Which of the following activities does NOT occur during parasympathetic stimulation?

During parasympathetic stimulation, the body engages in processes that promote rest and digestion. This is known as the "rest and digest" state. In this state, various physiological activities are enhanced, such as increased digestion, decreased heart rate, and enhancement of sexual arousal.

The fight-or-flight response, on the other hand, is a function of the sympathetic nervous system, which prepares the body to respond to perceived threats. This response includes increased heart rate, heightened alertness, and other physiological changes that enable quick action in stressful situations.

Thus, the option describing the fight-or-flight response is not associated with parasympathetic stimulation and correctly identifies an activity that does not occur in this state.
