Three factors that favor increased diffusion in the alveoli are the large surface area provided by the numerous alveoli, the thinness of the alveolar and capillary walls, and the presence of a concentration gradient. The extensive surface area allows for more gas exchange, while the thin walls facilitate quicker diffusion of gases. Additionally, a higher concentration of oxygen in the alveoli compared to the blood enhances the diffusion of oxygen into the bloodstream.
