Question

Ashley is on the track team and is running an 800-meter race. throughout the race, her respiratory rate increases rapidly. this occurred because her blood carbon dioxide levels ____ while oxygen levels ____

Answer 1

increase; decrease When you exercise, your body excretes carbon dioxide by automatically picking up carbon dioxide when your heart is pumping blood through your body. We use up more energy when we work out, so as a result, we get less oxygen and have to breathe harder to get the oxygen we need.

Answer 2

this occurred because her blood carbon dioxide levels increase while oxygen levels decrease.

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
