Verified step by step guidance

Begin by understanding the autonomic nervous system (ANS), which is a part of the peripheral nervous system responsible for regulating involuntary body functions such as heart rate, digestion, and respiratory rate.

Recognize that the ANS is divided into two main branches: the sympathetic nervous system and the parasympathetic nervous system.

The sympathetic nervous system is often referred to as the 'fight or flight' system, as it prepares the body to respond to stress or emergencies by increasing heart rate, dilating airways, and inhibiting digestion.

The parasympathetic nervous system is known as the 'rest and digest' system, as it conserves energy by slowing the heart rate, increasing intestinal and gland activity, and relaxing sphincter muscles in the gastrointestinal tract.

These two systems work in opposition to each other to maintain homeostasis in the body, ensuring that involuntary functions are balanced according to the body's needs.
