Question

What are the tiniest tubes in the lungs called and about how many do you have in total.

Answer 1

Bronchioles.

Step-by-step explanation:

The tiniest tubes are called bronchioles and there are about 30,000 of them in each lung. In your lungs, the main airways, called bronchi, branch off into smaller and smaller passageways. The smallest airways, called bronchioles, lead to tiny air sacs called alveoli.
