The autonomic nervous system is a part of the nervous system that controls the functions of the body that are not under voluntary control. It regulates the activities of internal organs such as the heart, lungs, stomach, intestines, liver, pancreas, kidneys, bladder, and reproductive organs. The autonomic nervous system is further divided into two subdivisions, the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system is responsible for the fight-or-flight response, which prepares the body for physical exertion or emergency situations. The parasympathetic nervous system is responsible for the “rest and digest” response, which promotes relaxation, digestion, and other bodily functions that occur during rest. Overall, the autonomic nervous system plays a critical role in maintaining homeostasis, or stable internal conditions, within the body.
