What is the narrow air passage located beneath each concha known as?

The narrow air passage located beneath each concha is referred to as a meatus. In the anatomy of the nasal cavity, the conchae (or turbinate bones) are structures that protrude into the nasal passages and serve to increase the surface area for air filtration, humidification, and warming. Each concha creates a corresponding meatus beneath it, allowing air to flow through the nasal cavity effectively while directing it toward the underlying sinuses and olfactory receptors. This arrangement facilitates the proper functioning of the respiratory system by ensuring efficient air passage and conditioning. Understanding the function and location of the meatuses is essential for comprehending how the nasal cavity contributes to respiratory health and fragrance detection.
