A large diffusion gradient - breathing ensures that the oxygen concentration in the alveoli is higher than in the capillaries so oxygen moves from the alveoli to the blood.

Answer:
This respiratory surface, also known as the respiratory membrane, includes the alveolar epithelial cells as well as the pulmonary capillary endothelial cells. Gas exchange is efficient due to a thin respiratory membrane, the high speed of diffusion, high surface area and lipid solubility of carbon dioxide and oxygen.
