The PNS is mainly responsible for managing homeostasis and SNS is mainly responsible for causing action, such as the fight or flight response. What T is the process of maintaining an internal temperature within a tolerable range, These specialised cells detect changes in temperature, What D is known as a serious reduction in the body's water content, What H is known as the amount of water vapor in the air, What H is known as abnormally high body temperature, What H is known as abnormally low body temperature, An increase in heart rate during exercise to compensate for a decrease in stroke volume. 10) Explain what is meant by the term 'cardiovascular drift'. However, if dehydration occurs during exercise, we see a reduction in blood plasma, resulting in the thickening of blood and a decreased distribution of blood to the skin.

This results in the hormone, angiotensin II being released, causing vasoconstriction, therefore increasing blood pressure and sodium uptake, along with increasing aldosterone hormone release, causing a rise in the uptake of water in the kidneys. Exercise in warm temperatures or for an extended period of time, Increased sweating, breathing,and muscle contraction results in loss of water, Water loss results in decreased blood plasma and thickening of theblood, Decreased blood plasma results in decreased in venous return, Decreased venous return results in decreased stroke volume, Decreased stroke volume results in decreased cardiac output, The heart compensates by increasing heart rate. The rise in cardiac output is a result of a rise in heart rate and stroke volume and the subsequent plateau is a result of an appropriate supply of oxygen to sustain the metabolic demands of the physical activity.

Although the exact mechanisms underlying cardiovascular drift are still unknown, two theories have been proposed. During exercise, vasodilation of the arterioles supplying the working muscles, skin,and heart occurs, increasing the supply of oxygen and nutrients. This increase lasts for the first 1 to 2 minutes of exercise, with the degree of increase relating to exercise intensity.
