CO₂ is the waste product of respiration of cells. Oxygen, on the other hand, is required in cellular respiration. Therefore at the alveolar in the lungs of an organism, CO₂ will be expelled while O₂ will be taken in.
Explanation:
This occurs passively due to the diffusion gradient, CO₂ usually has a higher concentration in the blood and lower concentration in alveoli hence this gas diffuses from the bloodstream into the lungs. On the other hand, oxygen is higher in concentration in the alveoli than in the blood capillaries hence difuses into the blood and taken to the cell for respiration. The CO₂ in the lungs is then expelled through exhalation of the lungs.
