Final answer:
The autonomic portion of the PNS functions without conscious effort. It controls the internal organs and glands of the body without conscious control.
Step-by-step explanation:
The autonomic portion of the PNS functions without conscious effort. The autonomic nervous system controls the internal organs and glands of the body, such as the lungs, heart, and smooth muscle, largely without conscious control. It continuously monitors these systems and implements changes as needed. The autonomic nervous system is divided into two opposing divisions: the sympathetic nervous system, which is involved in preparing the body for stress-related activities, and the parasympathetic nervous system, which is associated with routine day-to-day operations.
