4. If you just finished exercising, what happens to the amount of carbon dioxide you
exhale?!

More Carbon dioxide is removed from the blood and exhaled in the breath

Explanation:

During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest. The heart rate increases during exercise. The rate and depth of breathing increases - this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it. So, when you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide.
