ANATOMY

Detailed explanation-1: -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-2: -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-3: -Tiny hairs called cilia (pronounced: SIL-ee-uh) protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.

Detailed explanation-4: -Nostrils have fine hair called cilia and mucus to trap dust particles present in the inhaled air and stops them from entering our respiratory system.

Detailed explanation-5: -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. Between each ring of cartilage in your trachea, you have a muscle called the trachealis.
