Mucociliary Clearance

Mucociliary clearance is a natural defense process where tiny hair-like structures called cilia, lining the respiratory tract, move mucus and trapped particles out of the lungs and airways. The mucus acts as a sticky trap for dust, bacteria, and other harmful particles. The cilia beat in coordinated waves, pushing the mucus upward toward the throat, where it can be swallowed or expelled. This system helps keep the airways clean, preventing infections and irritation, and plays a vital role in respiratory health and clear breathing.
