Detailed explanation-1: -Overview. The bronchus in the lungs are lined with hair-like projections called cilia that move microbes and debris up and out of the airways. Scattered throughout the cilia are goblet cells that secrete mucus which helps protect the lining of the bronchus and trap microorganisms.
Detailed explanation-2: -Cilia are complex structures of the paranasal sinus mucosa in which its function is critical to respiratory defense. Cilia beat in a coordinated manner to clear the paranasal sinus cavities and upper airway of the mucus blanket that contains the pathogens and debris that are continually inspired in normal respiration.
Detailed explanation-3: -The cilia serve to transport dust and other foreign particles, trapped in mucous, to the back of the nasal cavity and to the pharynx. There the mucus is either coughed out, or swallowed and digested by powerful stomach acids. After passing through the nasal cavity, the air flows down the pharynx to the larynx.
Detailed explanation-4: -Cilia propel a liquid layer of mucus that covers the airways. The mucus layer traps pathogens (potentially infectious microorganisms) and other particles, preventing them from reaching the lungs.
Detailed explanation-5: -The cilia in the respiratory tract help move debris like microbes and dust out of the lungs.
