ANATOMY

Detailed explanation-1: -The peripheral nervous system is also divided into two parts: the somatic nervous system, which regulates the senses and voluntary muscle movement, and the autonomic nervous system, which controls involuntary body functions like blood flow, heartbeat, breathing, and digestion.

Detailed explanation-2: -The autonomic (ah-tuh-NOM-ik) nervous system controls processes that happen automatically (involuntarily), like breathing, digestion, sweating, and shivering. The autonomic nervous system has two parts: the sympathetic nervous system and the parasympathetic nervous system.

Detailed explanation-3: -The digestive system is made up of the digestive tract and other organs that help the body break down and absorb food. It is a long, twisting tube that starts at the mouth and goes through the oesophagus, stomach, small intestine, large intestine and anus.

Detailed explanation-4: -The parasympathetic nervous system (PSNS) is the division of the autonomic nervous system that facilitates resting, feeding or digesting and activating metabolism. It is one of the three divisions (sympathetic, parasympathetic, and enteric) of the autonomic nervous system.
