Dirt and bacteria are prevented from entering the alveoli primarily through the actions of the respiratory epithelium, which is lined with cilia and mucus. The cilia move in a coordinated manner to trap and expel particles and pathogens from the airways. Additionally, the mucus serves as a barrier, trapping foreign substances, while immune cells within the respiratory system help to neutralize any pathogens that may enter. This combination of physical and immune defenses protects the delicate alveolar structures from contamination.
