The sympathetic and parasympathetic nervous systems are two branches of the autonomic nervous system that control involuntary bodily functions. The sympathetic system is responsible for the body's "fight or flight" response, triggering the release of adrenaline and other stress hormones in response to a perceived threat. The parasympathetic system, on the other hand, is responsible for the "rest and digest" response, promoting relaxation and the conservation of energy. Together, these two systems work to maintain a balance in the body's functions and responses to stimuli.
The sympathetic nervous system prepares the body for "fight or flight" responses, while the parasympathetic nervous system promotes "rest and digest" activities. They work together to maintain physiological balance by regulating various bodily functions such as heart rate, digestion, and respiration.
