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: -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). The pharynx is part of two body systems (the respiratory system and the digestive system) because it carries both air and food.

Detailed explanation-3: -Epithelial cells help to protect or enclose organs; some produce mucus or other secretions. Certain types of epithelial cells have tiny hairs called cilia, which help remove foreign substances.

Detailed explanation-4: -The bronchus in the lungs are lined with hair-like projections called cilia that move microbes and debris up and out of the airways.

Detailed explanation-5: -Hair and cilia: Hair and cilia (tiny, hairlike structures) inside your nose trap dirt and particles. Then they move those particles toward your nostrils, where they can be sneezed out or wiped away.
