Detailed explanation-1: -Your parasympathetic nervous system is a network of nerves that relaxes your body after periods of stress or danger. It also helps run life-sustaining processes, like digestion, during times when you feel safe and relaxed.

Detailed explanation-2: -The parasympathetic nervous system decreases respiration and heart rate and increases digestion. Stimulation of the parasympathetic nervous system results in: Construction of pupils. Decreased heart rate and blood pressure.

Detailed explanation-3: -In the heart, parasympathetic stimulation of M2 receptors causes decreased heart rate and velocity of conduction through the AV node. In the vasculature, parasympathetic stimulation of M3 receptors leads to vasodilation. In the lungs, parasympathetic stimulation of M3 receptors leads to bronchoconstriction.
