MICROANATOMY

Detailed explanation-1: -The role of the nasal cavity is to humidify and warm the inspired air. Also, as the air passes through, the nasal cavity removes minute airborne particles and other debris before the air reaches the lower airways.

Detailed explanation-2: -The normal function of the body’s upper airway is to filter, humidify and warm the air we breathe in. Air is warmed by passing over a vast network of capillaries in the nose. Mucous membranes line the upper airways and help to moisten the air and trap airborne particles (dust and microbes).

Detailed explanation-3: -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.
