The autonomic nervous system (ANS) (or visceral nervous system) is the part of the peripheral nervous system that acts as a control system, maintaining homeostasis in the body.
The autonomic nervous system is a regulatory structure that helps people adapt to changes in their environment. It adjusts or modifies some functions in response to stress.
The organs (the "viscera") of our body, such as the heart, stomach and intestines, are regulated by a part of the nervous system called the autonomic nervous system (ANS).
