Question

Quizplus · Accepted Answer

The parasympathetic nervous system is responsible for returning the body to a normal state after the fight or flight response of the sympathetic nervous system has been activated. In this scenario, Malcolm's body responded with increased heart rate and shallow breathing due to the activation of his sympathetic nervous system. Once he realized there was no threat, his parasympathetic nervous system would have helped him relax and return to a normal state.
