According to the research, the correct option is bronchiole. The small passageway that ends in several alveoli is called bronchiole.
<h3>What is bronchiole?</h3>
They are tiny structures or flexible ducts that end in the alveolar bronchioles, and these, in the alveolar sacs, transporting the air we breathe to the pulmonary alveoli, where hematosis occurs.
These small airways of one millimeter or less, into which the distal bronchial tree is divided, are made up of a single layer of low ciliated or cuboidal cylindrical cells, goblet cells.
Therefore, we can conclude that according to the research, the correct option is bronchiole. The small passageway that ends in several alveoli is called bronchiole.
