검증된 단계별 안내

Understand that the sympathetic nervous system is part of the autonomic nervous system, responsible for the body's 'fight or flight' response.

Recognize its role in increasing heart rate, dilating airways, and redirecting blood flow to muscles during stress or danger.

Note that it uses neurotransmitters like norepinephrine to activate target organs and tissues.

Identify its effects on energy mobilization, such as breaking down glycogen and releasing glucose into the bloodstream.

Remember that it works in opposition to the parasympathetic nervous system, which promotes 'rest and digest' functions.
