Explanation: 

Detailed explanation-1: -The parasympathetic part of your autonomic nervous system balances your sympathetic nervous system. While your sympathetic nervous system controls your body’s “fight or flight” response, your parasympathetic nervous system helps to control your body’s response during times of rest.

Detailed explanation-2: -The parasympathetic nervous system, also known as “rest and digest, ” can be thought of as functioning in opposition to the sympathetic nervous system. Its functions include: A decrease in heart rate and contractility of cardiac muscle. Constriction of the ciliary muscle and the pupil for near vision.

Detailed explanation-3: -It is called the “rest and digest” division of the ANS. The parasympathetic nervous system decreases respiration and heart rate and increases digestion.

Detailed explanation-4: -Examples of parasympathetic responses This stands for: Salivation: As part of its rest-and-digest function, the PSNS stimulates production of saliva, which contains enzymes to help your food digest.

Detailed explanation-5: -The parasympathetic nervous system (PSNS) is part of your autonomic nervous system, which regulates your automatic body functions, such as heart rate, metabolism, and body temperature. Your PSNS is all about slowing your body down, helping it to relax and rebalance, especially after anything stimulating has occurred.
