The hollow space behind the nose that is divided medially by the nasal septum is the nasal cavity.

The nasal cavity is an essential part of the respiratory system. It serves several functions: it filters, warms, and moistens the air we breathe; it plays a critical role in our sense of smell; and it aids in resonating sounds for speech. The cavity is lined with mucous membranes that produce mucus, which helps trap dust and pathogens. The nasal septum, which is composed of cartilage and bone, divides the cavity into two nostrils, allowing for the passage of air to the lungs. Additionally, the nasal cavity connects to the paranasal sinuses, which can also affect breathing and sinus health.
