The _____ nervous system conserves energy, while the sympathetic nervous system consumes energy.
Fudgin [204]

The nervous system conserves energy, while the sympathetic nervous system consumes energy.

<h3>What is the nervous system?</h3>

The nervous system is an organ system that coordinates the activities of muscles, monitors organs, constructs and processes data received from the senses and initiates actions.

The nervous system can either be the following;

  • Sympathetic
  • Parasympathetic

The sympathetic nervous system is a part of the autonomic nervous system that raises blood pressure and heart rate, constricts blood vessels, and dilates the pupils when under stress.

On the other hand, the parasympathetic nervous system is one of the divisions of the autonomic nervous system, based between the brain and the spinal cord, that slows the heart and relaxes muscles.

This suggests that the parasympathetic nervous system conserves energy because it slows the heart while the sympathetic nervous system consumes energy.
