Alveoli are adapted for gas exchange due to their highly folded walls and being tightly packed, which increases surface area for diffusion, and their one-cell thick epithelium, reducing the diffusion distance.
Gli alveoli sono adattati allo scambio gassoso grazie alle loro pareti altamente pieghettate e all'essere strettamente compatti, che aumentano l'area superficiale per la diffusione, e al loro epitelio a una cellula di spessore, che riduce la distanza di diffusione.
