The function of the respiratory organ is to dump the carbon dioxide and to pick up the oxygen. The oxygen will be used to make energy, producing carbon dioxide as a side product. When Ashley exercise, the amount of energy needed increases so there is more oxygen used and more carbon dioxide produced.
This will induce the respiratory organ to increase its function by increasing the respiratory rate</span>
