The Alveoli And finally, at the ends of the smallest bronchioles are clusters of spherical structures that look a lot like bunches of grapes.
Alveoli clusters create a honeycomb-like structure The average human lung has about million alveoli with a combined inner surface area that is about the same size as half of a full-size tennis court.
