Quizplus · Accepted Answer

Epinephrine, also known as adrenaline, is responsible for the fight or flight response in stressful situations. It increases heart rate, blood pressure, and breathing rate, preparing the body to react to a perceived threat. In this case, Will's reaction of slamming the brakes hard to avoid hitting the man was a result of the release of adrenaline in response to the perceived danger.
