Nasal cavity: Anatomy • Lined by

Nasal cavity Anatomy • Lined by pseudostratified columnar epithelium with cilia • Inferior portion is larger than superior portion • Olfactory epithelium is located at the superior part of the nasal cavity around the cribriform plate Piriform aperture • Anterior opening bounded by the nasal bones and maxilla Nasal septum • Frequently deviates to 1 side, giving rise to unequal chambers Lateral walls • Composed of large venous plexuses that have the appearance of erectile tissue ... The nasal cavity is a large, air-filled space located above and behind the nose in the middle of the face. As the primary entry point for air into the respiratory system, it performs several crucial functions: Air Conditioning: It warms and humidifies inhaled air to protect the delicate tissues of the lower respiratory tract. Filtration: Hairs in the vestibule and the mucus lining trap dust, pollen, and other airborne particles. Sense of Smell: The olfactory region at the top of the cavity ... The nasal cavity includes the bones, tissues, and other structures that make up the inside of the nose. It warms and humidifies the air you breathe. 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 ...
