What Is the Function of Bronchioles?

Q:
What is the function of bronchioles?

A:
There are tubes split again and again inside your lungs like the branches of a tree. The smallest of those branches are called bronchioles, and they end in tiny air sacs called alveoli. The alveoli are where the oxygen is picked up by your blood.

Bronchioles contract and dilate, effectively controlling the flow of air as it makes its way to the alveoli.
