Answer :

Final answer:

The autonomic nervous system controls vital bodily functions involuntarily.


Explanation:

Autonomic nervous system (ANS) is a division of the peripheral nervous system responsible for maintaining homeostasis in the body by controlling functions like heart rate, digestion, and breathing.

The ANS operates largely involuntarily, regulating activities such as salivation, perspiration, and urination.

It consists of the sympathetic and parasympathetic branches, coordinating responses to internal and external stimuli to ensure the body functions optimally.
