The main stem of this branch of grapes is the trachea. They then branch into smaller ducts called bronchi.

These bronchi/stems branch into even smaller branches/stems called bronchioles.

The bundle of grapes are the alveolar sacs that stem from alveolar ducts/bronchioles.

Each grape represents an alveolus. This is where the gas exchange occurs.

This is the path that air travels when you inhale.
