PATHOLOGY

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: -Air enters the respiratory system through the nose. As the air passes through the nasal cav ity, mucus and hairs trap any particles in the air. The air is also warmed and moistened so it won’t harm delicate tissues of the lungs.

Detailed explanation-3: -The Paranasal Sinuses Surround the Nasal Cavities Mucosae line the paranasal sinuses and help to warm and humidify the air we inhale.
