Final answer:
The parasympathetic nervous system promotes rest and digestion and is part of the autonomic nervous system, opposing the fight-or-flight functions of the sympathetic nervous system.
Step-by-step explanation:
The correct statement about the parasympathetic nervous system is that it promotes rest and digestion. This system is part of the autonomic nervous system, which also includes the sympathetic nervous system; however, they have opposite functions. While the sympathetic nervous system is responsible for the fight-or-flight response during stressful situations, triggering the release of adrenaline and preparing the body for emergency actions, the parasympathetic nervous system calms the body down after such events. It slows down the heart rate, stimulates digestive activities, and generally conserves and restores energy.In response to the question, the correct statement about the parasympathetic nervous system is c) It promotes rest and digestion.
The parasympathetic nervous system is responsible for the body's rest and digest response. It works in opposition to the sympathetic nervous system, which is responsible for the fight or flight response. When the parasympathetic system is activated, it slows down heart rate, constricts blood vessels, stimulates digestion, and promotes relaxation.Examples:When you eat a meal, the parasympathetic nervous system helps stimulate the release of digestive enzymes and increases blood flow to the digestive organs.
