MICROANATOMY

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: -Tiny hairs in the nose called cilia (SIL-ee-uh) filter out dust and other particles. The nasal cavity and mouth join at the area in the back of the throat called the pharynx (FAR-inks).

Detailed explanation-3: -Cilia, tiny muscular, hair-like projections on the cells that line the airway, are one of the respiratory system’s defense mechanisms.

Detailed explanation-4: -Cilia, microscopic hairlike structures found along the bronchi (air passages throughout the lungs), are the first line of defense against environmental pollutants, viruses and bacteria.

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.
