Question
What is the missing word?
__________ cells move mucus and dust particles out of the trachea.
Solution
The missing word is "Ciliated." Ciliated cells line the respiratory tract, including the trachea, and play a crucial role in maintaining respiratory health. These specialized cells have tiny hair-like structures called cilia on their surface. The cilia work in a coordinated fashion to move mucus, which traps dust, pathogens, and other particles, upward towards the throat. This process, known as mucociliary clearance, helps keep the airway clear and prevents infections by ensuring that inhaled contaminants are expelled from the respiratory system. Therefore, the complete sentence reads: "Ciliated cells move mucus and dust particles out of the trachea."
