Nasal cavity is where respiration starts
Filtering, warming, let's go through its parts
Frontal bone's nasal part, strong shield
With nasal bones, protection they yield
Max-ill-a forms floor, side walls too
Pal-a-tine behind, air passage true
Vomer and ethmoid's perpendicular plate
Form septum, airflow they separate
Crib-ra-form plate, a porous screen
Olfactory nerves pass, unseen
Ethmoid's conchae, middle and superior
Increase surface area, nothing inferior
Inferior conchae, bones on their own
Turb-in-ates three, in each zone
Moisten and filter, temperature control
Air conditioning's their primary role
Sphenoid bone, at cavity's rear
Its sinus opens, drainage clear
Sphe-noid-al rostrum anchors septum's base
Stabilizing structure in this bony space
Lac-ri-mal bones, small but key
House na-so-lac-ri-mal ducts, you see
Tears drain from eyes to nasal floor
Maintaining moisture evermore
Co-ayne-ah, where nose meets throat Faren-gee-al es-mas, transition note From external nares to internal too Air's path complex, not just passing through
Nasal valve, where airflow's controlled External and internal, structure bold Naso-pharynx, where air and ear connect Eustachian tube, middle ear protect
Olfactory bulb sits just above Crib-ra-form's holes, perfect fit like a glove Mucosa lines all, with cilia fine Trapping particles, keeping air clean, sublime
Trigeminal nerve, sensory input high Facial nerve, parasympathetic supply Olfactory, smells it does perceive In nasal cavity, functions interweave
Nasal cycle, congestion alternates Every few hours, airflow it regulates From first breath to last scent we receive Nasal cavity's complexity we can't misconceive
