Chapter 14, Problem L2.1b
Using 20 or fewer words, define each of the following terms in your own words.
b. Parasympathetic nervous system
Verified step by step guidance1
The parasympathetic nervous system is part of the autonomic nervous system responsible for 'rest and digest' functions.
It conserves energy by slowing heart rate, increasing digestion, and promoting relaxation.
Parasympathetic responses are mediated by neurotransmitters like acetylcholine.
It primarily acts through cranial and sacral nerves to regulate involuntary processes.
Key organs affected include the heart, lungs, digestive tract, and glands.

Function of the Parasympathetic Nervous System
Autonomic Nervous System
The autonomic nervous system regulates involuntary bodily functions, including heart rate, digestion, and respiratory rate, and consists of the sympathetic and parasympathetic systems.

Rest and Digest
The 'rest and digest' response refers to the body's state of relaxation and recovery, facilitated by the parasympathetic nervous system, enhancing bodily functions like digestion.
