Detailed explanation-1: -In the nostrils, air gets warmed and moistened. 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-2: -Turbinates (conchae): There are three pairs of turbinates located along the sides of both nasal cavities. These folds inside your nose help warm and moisten air after you breathe it in and help with nasal drainage.

Detailed explanation-3: -Nose. The nose detects odor molecules and helps filter and warm the air we inhale. The upper respiratory system, or upper respiratory tract, consists of the nose and nasal cavity, the pharynx, and the larynx.

Detailed explanation-4: -The nose and trachea Breathing in through the nose warms and humidifies the air that is breathed in. Nose hairs help to trap any particles of dust. The warmed air enters the lungs through the windpipe, or trachea.

Detailed explanation-5: -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.
