Which division of the autonomic nervous system promotes rest-and-digest functions and conserves energy?
Correct Answer:
Parasympathetic Nervous System
Explanation:
The parasympathetic division of the autonomic nervous system is responsible for rest-and-digest and energy conservation. It promotes calming activities: slowing the heart rate, increasing digestive processes, and facilitating tissue repair and energy storage. This contrasts with the sympathetic division, which prepares the body for action (fight-or-flight), and with the somatic nervous system, which controls voluntary muscles. Since the question asks which division promotes rest and energy conservation, the parasympathetic nervous system is the best fit.
