Exercise and emergency reactions include ________.

Question

Quizplus · Accepted Answer

Exercise and emergency reactions both involve increased activity in the sympathetic division of the autonomic nervous system, which prepares the body for physical activity and stress. This increased activity includes increased heart rate, respiration, and blood pressure. At the same time, there is decreased activity in the parasympathetic division, which is responsible for rest and digestion. This combination of increased sympathetic and decreased parasympathetic activity is what allows the body to respond appropriately to exercise or emergency situations.
