Removal of CO 2 from the Lungs C 6 H 12 O 6 + 6O 2 6CO 2 + 6H 2 O + Energy Aerobic respiration diffuses into the blood plasma Carried in the form of “ hydrogen carbonate ions (HCO 3 - )” blood passes through the lungs hydrogen carbonate CO 2 + H 2 O convert In the Lungs, CO 2 concentration is low,
15. Removal of CO 2 from the Lungs hydrogen carbonate CO 2 + H 2 O convert diffuses out of the blood capillaries into the alveolar cavities for exhalation CO2 CO 2 O 2
