During periods of high muscle activity muscles need more oxygen requiring the respiratory system to work harder (a person breaths harder) to take in more oxygen. This oxygen is taken to the muscle via the circulatory system. During periods of high muscle activity heart rate increases which causes the circulatory system to deliver the oxygen and nutrients to the muscles at a faster rate. Since the muscles are working hard they also produce waste chemicals and heat more rapidly. The circulatory system deals with this problem by releasing the heat through veins near the skin. The increased rate of the circulatory system also allows waste chemicals such as carbon dioxide to leave the body at a faster rate because it is delivered back to the lungs at a increased rate. Once at the lungs the carbon dioxide is traded for oxygen.
