Answer 2

breathing provides your body with necessary oxygen, but it also rids the body of waste like carbon dioxide. To get rid of carbon dioxide, your blood delivers it to the capillaries surrounding your alveoli. In the alveoli, the carbon dioxide moves into the lungs, where it leaves the body when you exhale.
