Final answer:
Air enters our body through the nasal cavity, pharynx, larynx, and trachea, before reaching the bronchi, bronchioles, and alveoli for gas exchange.
Step-by-step explanation:
The correct order of airflow during inhalation is: nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, alveoli. When we breathe in, air enters our body through the nasal cavity, passes through the pharynx, larynx, and trachea, and then enters the bronchi. From the bronchi, it further branches into smaller bronchioles, finally reaching the alveoli for gas exchange with the blood.
