Question

Quizplus · Accepted Answer

The sympathetic nervous system is responsible for the "fight or flight" stress response. It is part of the autonomic division of the peripheral nervous system, which is responsible for involuntary functions like heart rate, digestion, and breathing. When triggered by a stressful or dangerous situation, the sympathetic nervous system prepares the body for action by increasing heart rate, dilating pupils, and redirecting blood flow to muscles, among other things.
