bronchiole

[brong′kē·ōl]

Etymology: L, bronchiolus, little windpipe

a small airway of the respiratory system extending from the bronchi into the lobes of the lung. There are two divisions of bronchioles: The terminal bronchioles passively conduct inspired air from the bronchi to the respiratory bronchioles and expired air from the respiratory bronchioles to the bronchi. The respiratory bronchioles function similarly, allowing the exchange of air and waste gases between the alveolar ducts and the terminal bronchioles. bronchiolar [brongkē′ələr] adj.

bronchiole [brong´ke-ōl]

one of the successively smaller channels into which the segmental bronchi divide within the bronchopulmonary segments. adj., adj bronchi´olar.

respiratory b's the final branches of the bronchioles, communicating directly with the alveolar ducts; they are subdivisions of terminal bronchioles, have alveolar outcroppings, and themselves divide into several alveolar ducts.

Respiratory bronchiole. From Dorland's 2000.

( and see color plates.)

terminal bronchiole the last portion of a bronchiole that does not contain alveoli, i.e., one whose sole function is gas conduction; it subdivides into respiratory bronchioles.
