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.

Detailed explanation-3: -When the parasympathetic nervous system (PSNS) is activated, it slows our heart and breathing rates, lowers blood pressure and promotes digestion. Our body enters a state of relaxation, and this relaxation breeds recovery.

Detailed explanation-4: -The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal. It contains three anatomically distinct divisions: sympathetic, parasympathetic, and enteric.

Detailed explanation-5: -The parasympathetic nervous system is responsible for the body’s rest and digestion response when the body is relaxed, resting, or feeding. It basically undoes the work of sympathetic division after a stressful situation. The parasympathetic nervous system decreases respiration and heart rate and increases digestion.
