Solution
D: a mixture of gases that has more carbon dioxide than inhaled air
When we exhale, we breathe out less oxygen but more carbon dioxide than we inhale. The carbon we breathe out as carbon dioxide comes from the carbon in the food we eat. ... The carbon dioxide is dissolved in the blood, carried to the lungs by the circulation, and breathed out
