Describe the path air must take to reach the lungs?

Answer 1

Through the nasopharynx, past the oropharynx and laryngopharynx into the trachea. From there it will travel down one of two bronchi into a smaller bronchiole and eventually into an alveolar sac.

Answer 2

In through the mouth, through the esophagus, and into the lungs. Hope this helps.
