Quizplus · Accepted Answer

When Amanda relaxes and her heart rate and breathing rate return to normal, it suggests that her parasympathetic nervous system is active and releasing acetylcholine. The parasympathetic nervous system opposes the "fight or flight" response of the sympathetic nervous system, resulting in decreased heart rate and breathing rate. Acetylcholine is the primary neurotransmitter released by the parasympathetic nervous system.
