The process by which the body controls and maintains a balanced state that is controlled by the ANS
Autonomic nervous system
Actions of the ANS are automatic, we do not have conscious control over them. For example we do not think about breathing or our heartbeat, these things just happen
Sympathetic nervous system
Works with the PNS to keep the body balanced, A state of physical arousal such as breathing rate and sweating, this system prepares the body for fight or flight
Parasympathetic nervous system
Counteracts the actions of the SNS, produces the opposite effects such as the reducing of the heart rate, allows the body to return to its normal resting state
