During a physical workout ones physical appearance is flushed red, warm to the touch, and perspiration is usually all over and give the person a shiny tint. All of these are healthy reactions unlike the man who has cool, clammy, moist skin with beads of perspiration. The body has to work hard along with the heart during exercise, there is more blood pumped through the body with every beat and is continuously working at its maximum level. Valves inside the heart open and close which controls the amount of blood entering or leaving the heart. Extensive vascular enlargement happens as the oxygen increases in the skeletal muscles. While peripheral resistance decreases, blood flow in the capillaries is faster, and the blood enters the venous system faster.
This acceleration of the venous portion also makes blood flow faster to the skeletal muscles, cardiac muscles, and skin. Red skin shows the increased blood flow because the arteries and capillaries are becoming larger; also this is the same reason for the rise in body temperature. The cardiovascular system is the mechanism responsible for the changes in the appearance. While the blood to the heart and body is affected the blood supply to the brain is not. The gentleman’s body is experiencing the opposite of the person working out because blood flow throughout the body decreases causing the arteries and capillaries to clasp which in return makes the skin cool and clammy. He is still sweating because his body is trying to keep blood flowing but it is difficult and the body temperature is dropping. The cardiovascular system is a continuous process that is essential to homeostasis. It transports oxygen, carbon dioxide, blood cells, delivers nutrients and hormones: removes waste products; assists in temperature regulation and is a defense against disease.
