parasympathetic
The parasympathetic nervous system is a part of the autonomic nervous system, which controls involuntary bodily functions. It is often referred to as the "rest and digest" system because it helps the body relax and conserve energy after stressful situations. When activated, it slows the heart rate, increases digestive activity, and promotes relaxation.
This system works in opposition to the sympathetic nervous system, which prepares the body for "fight or flight" responses. The balance between these two systems is essential for maintaining homeostasis, allowing the body to respond appropriately to different situations and maintain overall health.
