After passing through the trachea, what is the next (human lung) anatomical structure that air would flow into?

Question 15 options:

Bronchioles

Nasal cavity

Larynx

Bronchus

Alveoli

During inhalation, air filtered and warmed by the upper respiratory system passes from the pharynx and larynx into the trachea, then down to the bronchi and into the lungs. Deoxygenated air from the lungs passes back up through the trachea during exhalation.
