After air passes through the trachea, which structure does it enter next?

Explanation:
Air moves next into the main airways called the bronchi. The trachea splits into two primary bronchi, one leading to each lung, and these bronchi then branch into smaller passages (bronchioles) before reaching the tiny air sacs (alveoli) where gas exchange happens. The larynx is before the trachea, so it isn’t the next structure after the trachea. The alveoli come much later in the pathway, after the bronchioles. Bronchioles are the next stage after the bronchi, but the immediate continuation after the trachea is the bronchi.
