Identify three reasons for an increased water loss during exercise. The PNS is mainly responsible for managing homeostasis and SNS is mainly responsible for causing action, such as the fight or flight response. Furthermore, when core body temperature increases the body responds by increasing skin blood flow to help control the temperature rise. During exercise, vasodilation of the arterioles supplying the working muscles, skin,and heart occurs, increasing the supply of oxygen and nutrients. A lack of blood at the skin decreases the sweating response, which in turn causes an increase in body temperature which if not lowered, in extreme cases can lead to heatstroke. the difference between the partial pressures of a gas at two points is known as what DG?
