A part of the autonomic nervous system that controls rest among other routine functions. It is also associated with returning the body to a relaxed state.

The Parasympathetic Nervous System

Activation of the parasympathetic nervous system leads to a series of physiological effects associated with 'rest and digest' functions. These include:
* Pupil constriction
* Stimulation of salivation
* Slowing of heart rate
* Constriction of bronchi
* Stimulation of digestion
* Stimulation of bile secretion
* Contraction of the bladder
