MICROANATOMY

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: -Cilia are complex structures of the paranasal sinus mucosa in which its function is critical to respiratory defense. Cilia beat in a coordinated manner to clear the paranasal sinus cavities and upper airway of the mucus blanket that contains the pathogens and debris that are continually inspired in normal respiration.

Detailed explanation-3: -Filters and cleans air to remove particles and allergens. Provides a sense of smell. Warms and moistens air so it can move comfortably into your respiratory system.

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. Scattered throughout the cilia are goblet cells that secrete mucus which helps protect the lining of the bronchus and trap microorganisms.

Detailed explanation-5: -The hair and mucus that are present inside the nose filter the air that goes into the lungs. That is, these stop the germs and dust from entering into our body.
