Cilia and Mucus Clearing

Cilia are tiny hair-like structures lining the respiratory tract that move rhythmically to help keep the airways clear. Mucus, produced by specialized cells, traps dust, germs, and other particles inhaled with air. The cilia beat in coordinated waves, sweeping the mucus along with trapped particles upward toward the throat, where it can be swallowed or coughed out. This process, known as mucociliary clearance, is essential for protecting the lungs from infections and maintaining healthy breathing. It’s a natural, efficient system that continuously helps keep the respiratory system clean and functioning properly.
