MEDICAL PHYSIOLOGY

Detailed explanation-1: -The parasympathetic system predominates during quiet, resting conditions. The overall effect of the parasympathetic system under these conditions is to conserve and store energy and to regulate basic body functions such as digestion and urination.

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: -Parasympathetic nervous system: This part of your autonomic nervous system does the opposite of your sympathetic nervous system. This system is responsible for the “rest-and-digest” body processes.

Detailed explanation-4: -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.
