Question

Quizplus · Accepted Answer

During exercise and emergency situations, the body activates the sympathetic branch of the nervous system which increases heart rate, blood pressure, and energy production. At the same time, the parasympathetic branch is decreased which slows down digestion and other non-essential functions. This response is commonly known as the fight or flight response. The other choices either do not accurately describe the physiological response or are not relevant to exercise and emergency reactions.
