This is true because the partial pressure of oxygen is higher in the alveoli than in the blood, and the partial pressure of carbon dioxide is higher in the blood than in the alveoli. This difference in partial pressure drives the diffusion of oxygen from the Show more…

Gas exchange in the lungs is efficient due to all of the factors below except: - Thin alveoli and capillary walls provide a short diffusion distance. - Substantial differences in partial pressures of O2 and CO2. - O2 and CO2 are lipid soluble gases. - Sheets of cartilage provide high compliance in the alveoli.

All of the following facilitate gas exchange in the lungs EXCEPT: (A) thin alveolar walls. (B) multiple subdivisions of the respiratory tree. (C) differences in the partial pressures of $\mathrm{O}_{2}$ and $\mathrm{CO}_{2}$ (D) active transporters in alveolar cells
