The purpose of the mucociliary escalator mechanism is to screen out, kill, and remove dust, dirt, and pathogens from inhaled air. The mechanism consists of cilia and mucus-producing cells in the respiratory tract that trap foreign particles, and the cilia move the mucus and particles up and out of the airways, preventing them from entering the lungs.
