MICROANATOMY

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: -The tissue that lines the nasal cavity, called the nasal epithelium, moistens, warms, and further cleanses the inhaled air. Nasal turbinates, or nasal conchae, are fingerlike projections inside the nasal cavity that increase the surface area for warming and moistening inhaled air.

Detailed explanation-4: -The mucous membranes in your mouth and nose warm and moisten the air, and trap particles of foreign matter (like dirt and dust). The air passes through the throat into the trachea (windpipe).
