Each primary or main bronchus ventilates one
WebEach respiratory bronchiole supplies the alveoli held in each acinus accompanied by a pulmonary artery branch. The pulmonary lobule is the portion of the lung ventilated by one bronchiole. Bronchioles are approximately 1 mm or less in diameter and their walls consist of ciliated cuboidal epithelium and a layer of smooth muscle. WebYour bronchi have two main (or primary, or first) parts: Right main bronchus is a short, wide air passageway into your right lung. Left main bronchus is a narrow, long passageway into your left lung. Your right and left main bronchi are the widest portions of your bronchi.
