Explanation:
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: -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.
