Moving mucus out of the lungs.
Cilia beat in coordinated waves to propel mucus (which traps inhaled particles and microbes) up toward the throat for swallowing or expectoration—the mucociliary escalator. They do not directly kill pathogens or produce antimicrobial fluids, and their main role is not signaling for immune cells.
