Nasal cavity: The role of the

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. Columnar epithelium lines the nasal cavity. This type of epithelial lining also secretes mucus that coats the lining and helps with the mucociliary clearance of minute aerosolized particles that become trapped in the nasal mucosa. The nasal cavity also functions to facilitate ... This is an article covering the anatomy of the nasal cavity, its parts, blood supply and innervation. Learn all about it at Kenhub! The nasal cavity and nearby sinuses are lined with nasal mucosa, which warms and moistens inhaled air. Shell-like bones called nasal conchae assist in the air-warming process. Tiny hairs in the nostrils trap large particles, preventing them from entering the lungs. The nose triggers sneezing to expel irritating particles. It constitutes the upper respiratory system and the paranasal sinuses, oral cavity, pharynx, and larynx and is the first of the respiratory tract structures.
