What is the parasympat?

Answer 1

The parasympathetic nervous system is a part of the autonomic nervous system responsible for regulating involuntary bodily functions during restful states. It promotes "rest and digest" activities, such as slowing the heart rate, increasing intestinal and gland activity, and relaxing sphincter muscles. This system helps conserve energy and restore body functions after stress or activity. Its primary neurotransmitter is acetylcholine, which facilitates communication between nerve cells and target organs.
