Detailed explanation-1: -Your parasympathetic nervous system’s job is usually to relax or reduce your body’s activities. Because of the signals it carries, the rhyming phrases “rest and digest” or “feed and breed” are easy ways to remember what your parasympathetic nervous system does.
Detailed explanation-2: -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.
Detailed explanation-3: -In the stomach and intestines, parasympathetic stimulation of M receptors leads to increased motility and relaxation of sphincters. Stimulation of M receptors also increases gastric secretions to aid in digestion. In the gallbladder, parasympathetic stimulation of M3 receptors stimulates contraction to release bile.
