During Parasympathetic Nervous System?

The parasympathetic nervous system controls bodily functions when a person is at rest. Some of its activities include stimulating digestion, activating metabolism, and helping the body relax.

What happens during parasympathetic nervous system activity?

The parasympathetic nervous system is responsible for the body's rest and digestion response when the body is relaxed, resting, or feeding. It basically undoes the work of sympathetic division after a stressful situation. The parasympathetic nervous system decreases respiration and heart rate and increases digestion.

What does the parasympathetic nervous system releases?

Preganglionic neurons of the sympathetic and parasympathetic divisions and postganglionic neurons of the parasympathetic nervous system utilize acetylcholine (ACh). Postganglionic neurons of the sympathetic nervous system use norepinephrine and epinephrine. Although, there are exceptions to this as described below.
