Here's a breakdown:
* Nasal cavity: This is the large, hollow space inside your nose. It's lined with a mucous membrane that helps to trap dust, dirt, and other particles.
* Nasal septum: This is the wall of cartilage and bone that divides the nasal cavity into two chambers.
* Conchae: These are bony projections that stick out from the side walls of the nasal cavity. They help to increase the surface area of the nasal cavity and create turbulence in the air as you breathe. This turbulence helps to warm, moisten, and filter the air before it reaches your lungs.
* Sinuses: These are air-filled cavities within the bones of your skull that connect to the nasal cavity. They also contribute to the overall resonance of your voice.
The nasal cavity plays an important role in breathing, smell, and speech.
