Question 16

Explain how ciliated cells keep the lungs clear from dust and mucus.

Answer 16

Cilia Movement: Ciliated cells have tiny, hair-like structures called cilia on their surface. These cilia constantly move in a coordinated wave-like motion.

Transporting Mucus: The cilia push mucus, which traps dust, dirt, and microbes, upward toward the throat.

Expelling Mucus: Once the mucus reaches the throat, it is either swallowed or coughed out, removing the trapped particles from the lungs.
