Question

Quizplus · Accepted Answer

During the fight or flight reaction, the sympathetic division increases the activity of certain organs to allow a greater expenditure of energy for both physical and mental exertion. For example, sympathetic stimulation increases heart rate and the force of myocardial contraction; also bronchodilation allows for more air exchange in the lungs. At the same time, there is a decrease in the activity of the organs whose functions are not required for the fight or flight reaction. For example, activity of the gastrointestinal and urinary tracts is inhibited.
