Question

Quizplus · Accepted Answer

The sympathetic nervous system is responsible for the body's "fight or flight" response to stressful or dangerous situations, such as the one Molly experienced. It triggers the release of adrenaline and other stress hormones, which increase heart rate, respiration, and blood pressure, and mobilize energy stores for quick use. The other options are not involved in this type of emergency response.
