Detailed explanation-1: -The major function of the nose is to warm and humidify air before it reaches to the lungs for gas exchange. Conditioning of inspired air is achieved through evaporation of water from the epithelial surface. The continuous need to condition air leads to a hyperosmolar environment on the surface of the epithelium.

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: -Nasal turbinates, or nasal conchae, are fingerlike projections inside the nasal cavity that increase the surface area for warming and moistening inhaled air.
