What is the naval cavity?

The nasal cavity is a hollow space within the nose that is lined with mucous membranes and cilia. It plays a crucial role in respiration by filtering, warming, and humidifying the air we breathe. The nasal cavity is also involved in the sense of smell and connects to the paranasal sinuses, which help reduce the weight of the skull and enhance resonance of the voice. Additionally, it serves as a pathway for air to reach the throat and lungs.
