What it means
The hollow inside the nose, split into right and left halves by the nasal septum. It is lined with a moist membrane and tiny hairs that warm, wet and filter the air before it reaches the lungs, and it holds the nerve endings for smell. It opens into the sinuses and, at the back, into the throat.
