Verified step by step guidance1
Understand the role of the autonomic nervous system (ANS) in regulating involuntary bodily functions, including digestion.
Recognize that the ANS is divided into two main branches: the sympathetic nervous system and the parasympathetic nervous system.
Learn that the sympathetic nervous system is responsible for the 'fight or flight' response, which generally inhibits digestion by redirecting energy to muscles and vital organs.
Identify the parasympathetic nervous system as the branch that promotes 'rest and digest' activities, enhancing digestion by stimulating digestive secretions and peristalsis.
Note that the somatic nervous system controls voluntary movements and is not involved in digestion, while the central nervous system processes information but does not directly control digestion.
