ANATOMY AND PHYSIOLOGY OF THE NASAL CAVITY: STRUCTURE, FUNCTION, AND CLINICAL SIGNIFICANCE

The nasal cavity is a key anatomical structure of the human respiratory system, responsible for air conduction, filtration, humidification, and temperature regulation. This study examines the anatomical organization and physiological functions of the nasal cavity, emphasizing its clinical significance in maintaining respiratory health. The nasal cavity is lined with specialized mucosa that contains ciliated epithelium and goblet cells, which play a crucial role in mucociliary clearance and protection against pathogens. Its complex internal structure, including nasal conchae, increases surface area and enhances air conditioning efficiency. Through a detailed review of anatomical and physiological data, this paper highlights the relationship between structure and function in the nasal cavity. Understanding these features is essential for clinical practice, particularly in the diagnosis and treatment of respiratory diseases such as rhinitis, sinusitis, and nasal obstruction.
