alveoli.

Explanation:

The trachea (windpipe) branches into two primary bronchi at its lower end. Each primary bronchus leads to a lung. Secondary bronchi branch from primary bronchi (after the primary bronchi enter the lungs), bronchioles are smaller branches from bronchi, and alveoli are the tiny air - sacs at the end of the bronchial tree.

Answer:

primary bronchi.
