Explanation: 

Detailed explanation-1: -The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal. It contains three anatomically distinct divisions: sympathetic, parasympathetic, and enteric.

Detailed explanation-2: -The main functions of the PNS are voluntary movements such as chewing food, walking, and facial expressions. The PNS also regulates autonomic functions such as breathing, heart rate, and digesting – the unconscious bodily behaviors. The PNS is thus especially important for humans to survive.

Detailed explanation-3: -The PNS is made up of two divisions: the somatic nervous system and the autonomic nervous system. The somatic system contains sensory and motor neurons. It sends and receives sensory information and motor signals. The autonomic system is responsible for regulating involuntary body functions.
