Ciliary action

Ciliary action refers to the coordinated movement of tiny hair-like structures called cilia that line certain parts of the body, such as the respiratory tract. These cilia beat rhythmically, creating a wave-like motion that helps move mucus, trapped dust, and pathogens out of the lungs and airways. This process is essential for keeping the respiratory system clean and preventing infections. The movement is highly organized and relies on microscopic structures within each cilium that generate the force needed for this synchronized beating, functioning much like small oars rowing in unison.
