Question

write
a flow chart shows the pathway of air
in breathing, write the changes that occur in
nasal cavity in inhalation,​

Answer 1

The air enters nasal chamber through nostrils then moves to pharynx->larynx->trachea->bronchus->bronchi->bronchioles and finally to alveoli. When air enters nasal cavity the dust particles are trapped. I hope this is the only change that occurs in nasal cavity.
