Fight or flight: which division of the autonomic nervous system is responsible for this response?

Explanation:
The fight-or-flight response is driven by the sympathetic division of the autonomic nervous system. This branch activates quickly in response to perceived threats, increasing heart rate and blood pressure, dilating airways to improve breathing, redirecting blood to the muscles, releasing stored energy, and even producing sweat. All of this readies the body for rapid action. The parasympathetic division does the opposite, promoting rest and digestion, while the somatic nervous system controls voluntary muscle movements, not autonomic arousal.
