MICROANATOMY

Detailed explanation-1: -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: -In the nostrils, air gets warmed and moistened. Tiny hairs in the nose called cilia (SIL-ee-uh) filter out dust and other particles.

Detailed explanation-3: -Cilia are tiny hair-like structures on the surface of cells in many parts of the body, including the lungs. When they are functioning correctly, cilia beat together in a wave-like motion to move mucus, germs and other foreign particles up toward the mouth where they can be coughed or sneezed out.

Detailed explanation-4: -Hairlike structures called cilia line the mucous membrane and move the particles trapped in the mucus out of the nose. Inhaled air is moistened, warmed, and cleansed by the tissue that lines the nasal cavity.

Detailed explanation-5: -These tubes are called bronchi and bronchioles. All of these airways are lined by cells. The mucus they produce catches most of the dust particles. Tiny hairs called cilia, covering the walls of the air tubes, move the mucus upward and out into the throat, where it is either coughed up and spat out, or swallowed.
