Answer:
Pathway of air during respiration
The process of which a person takes one breath is called the respiratory cycle. The Nose: First, air enters your body either through your nose or your mouth, where it is then held in your nasal cavity/oral cavity. Once inside the nasal cavity, the air passes through the nasal conchae.
