The smallest branches of the bronchial tubes are called BRONCHIOLES, at the end of which are the air sacs or alveoli. the smallest passageways in the lungs are called the This is called exhalation. Normally, tiny hair-like structures known as cilia remove mucus and other substances from the lungs, and bacteria are cleared out. These then branch to give rise to several orders of progressively smaller airways called bronchioles, the smallest of which are called terminal bronchioles.
