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: -The trachea is also lined with cilia, which sweep fluids and foreign particles out of the airway so that they stay out of the lungs.
Detailed explanation-3: -When you inhale, the mucus traps dust or other small debris to keep it from traveling to your lungs. In the trachea’s inner layer, you have small, hair-like structures called cilia. Cilia move in rhythm to push mucus out of your trachea so that you either expel or swallow it.
