Anatom3DLeft side of internal nose
Latus sinistrum cavitatis nasi · Levá strana dutiny nosní
Skeleton
Looks like
One half of the nasal cavity, from one nostril back to the throat, bounded by the septum and the side wall.
What it does
Each side carries air on its own; the lining swells and shrinks alternately on the two sides every few hours.
Keeping it well
One side blocked for weeks, especially with bleeding or reduced smell, needs an endoscopic look by an ENT doctor.
