How Do Your Airways Move Mucus Out?

Airway mucus catches some inhaled material. Coordinated ciliary beating helps move it toward the throat, where it can be swallowed or expelled; this lining is different from the gas-exchange surface of alveoli.

Airway cutaways show mucus above cilia and compare high sweeping strokes with lower recovery strokes moving material toward the throat.

What the illustration shows

Educational poster titled “How Do Your Airways Move Mucus Out?” on a navy background. At left, gold arrows follow the bronchi into the trachea and upward toward the throat. A large cutaway labeled “Capture at the surface” shows particles caught in gold mucus gel above a blue periciliary layer surrounding coral cilia. Beneath are tall ciliated cells, pale granule-filled secretory cells, and small basal cells within one epithelial sheet above the basement membrane. The lower section, “Coordinated beating,” compares higher, rightward-sweeping cilia during the effective stroke with lower-bent cilia during recovery. A broad rightward arrow indicates net movement toward the throat. A note identifies this as a proximal-airway example, not the alveolar lining. Footer: AllHumanBody.com; “Real anatomy. Real knowledge. A healthier tomorrow.”
