Quizplus · Accepted Answer

The "mucus escalator" refers to the movement of mucus across the surface of the airways, which is facilitated by the coordinated beating of cilia on the surface of ciliated cells lining the airways. These ciliated cells play a crucial role in trapping and moving particles out of the airways, helping to keep the respiratory system clean.
