ANATOMY

Detailed explanation-1: -The mucus traps smaller particles like pollen or smoke. 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: -Mucus has a pretty important job-it keeps the lining of your nose moist and warms the air you breathe. Mucus also protects the lungs. When you breathe in air through your nose, it contains lots of tiny things, like dust, dirt, germs, and pollen.

Detailed explanation-3: -Mucus acts as a physical barrier, trapping inhaled particles and pathogens, whilst cilia move both the mucus layer and fluid in the underlying periciliary layer.

Detailed explanation-4: -Your nose is involved in several important bodily functions: Allows air to enter your body. Contributes to how you look and how you sound when you speak. Filters and cleans air to remove particles and allergens.

Detailed explanation-5: -Columnar epithelium lines the nasal cavity. This type of epithelial lining also secretes mucus that coats the lining and helps with the mucociliary clearance of minute aerosolized particles that become trapped in the nasal mucosa.
