The inferior meatus is a narrow passage located within the nasal cavity, specifically beneath the inferior nasal concha. It plays a crucial role in the drainage of tears from the eyes, as it is the opening for the nasolacrimal duct, which carries tears from the eye surface to the nasal cavity. This anatomical structure is important for maintaining proper nasal function and drainage. The inferior meatus also serves as a pathway for mucus to flow out of the nasal cavity, helping to keep the airways clear and moist. Its position and function are essential for overall respiratory health.
