The purpose of the mucociliary escalator mechanism is to screen out, kill, and remove dust, dirt, and pathogens from inhaled air before it reaches the lungs. The cilia and mucus lining the respiratory tract trap foreign particles and pathogens, which are then either expelled through coughing or swallowed and destroyed by stomach acid.
