the.com/nasal cavity
The body's air-conditioning duct, sloppily lined with mucus and marketed as a face feature.
means The hollow space behind your nose, lined with mucous membrane, that warms, moistens, and filters the air you breathe before it reaches your lungs.
from 'Nasal' traces back to the Latin 'nasus,' meaning nose — the same root that gives us 'nasturtium' (a plant whose peppery scent was said to make the nose wrinkle) and 'nostril' (from Old English 'nosu' plus 'thyrl,' a hole). 'Cavity' comes from Latin 'cavus,' meaning hollow, the same source behind 'cave' and 'concave.' Put together in anatomical Latin, the term simply describes exactly what it is: the hollow behind the nose, named with blunt medical honesty rather than poetry.
