"WebMammals have a circulatory system, so their size isn't limited by their gas exchange system. Because mammals breathe air, unwanted particles sometime get into the gas exchange system. There is mucus in the trachea and bronchioles to keep them clean and moist. The alveoli must stay moist so oxygen can dissolve and then diffuse into the blood.
