mucociliary transport

mucociliary clearance

the movement of the mucous covering of the respiratory epithelium by the beating of cilia: rapid, forward (effective) stroke and slow, return (recovery) stroke. In the nose, mucus is moved toward the pharynx. In the tracheobronchial tree, mucus is moved toward and through the larynx and swallowed.

(myū'kō-sil'ē-ar-ē trans'pōrt)
Movement of mucus and mucoid fluid through the bronchial tree by the action of cilia.

mucociliary

pertaining to a combination of cilia and mucus.

mucociliary blanket
a blanket of mucus overlying cilia beating in a watery sol on the surface of the respiratory mucosa.
mucociliary escalator
the nonimmunological defense mechanism involving ciliary action and flow of mucus from bronchioles, through the bronchi and trachea to the larynx, by which particulate matter is removed from the respiratory tract. Called also mucociliary ladder.
