Preferred Label : bronchiole;
Definition : Anatomy.—Bronchioles are non–cartilage-containing airways. Terminal bronchioles are
the most distal of the purely conducting airways; they give rise to respiratory bronchioles,
from which the alveoli arise and permit gas exchange. Respiratory bronchioles branch
into multiple alveolar ducts (30). Radiographs and CT scans.—Bronchioles are not identifiable
in healthy individuals, because the bronchiolar walls are too thin (4). In inflammatory
small-airways disease, however, thickened or plugged bronchioles may be seen as a
nodular pattern on a chest radiograph or as a tree-in-bud pattern on CT scans. [Fleischner
