Meanwhile, the waste-rich blood from the veins releases its carbon dioxide into the alveoli. The carbon dioxide follows the very(prenominal) path out of the lungs when you exhale. The hitchs job is t o do pump the carbon dioxide out of the lun! gs and pull the oxygen into the lungs. The diaphragm is a sheet of muscles that lies across the bottom of the chest cavity.
