The correct answer is: (option A) It calms the body and conserves energy.
• Parasympathetic Nervous System (PSNS) is a network of nerves that relaxes our body after times of stress or danger. We have it as a component of our automatic nervous system.
• Although it controls numerous functions that we do not have to think about, it is also possible to refer to it as the "automatic" nervous system. Control of the heartbeat, blood pressure, digestion, perspiration, etc. are included in this.
• The parasympathetic nervous system regulates the body's calmness and energy conservation. As the body conserves energy, pupils contract, heartbeat allows, blood pressure decreases, and digestion is stimulated.
• Our sympathetic nervous system is balanced by the parasympathetic portion of our autonomic nervous system. In moments when we feel secure or comfortable and at ease, it helps keep life-sustaining mechanisms running.
Therefore, the option that best describes the function of the parasympathetic nervous system is: (option A) It calms the body and conserves energy.
