Bronchi of Inferior Lobe of Left Lung

Description

The left inferior lobar bronchus provides an airway for the entire inferior lobe of the left lung. It arises as a branch of the left main bronchus and descends posterolaterally to enter the inferior lobe of the left lung. Initially, the left inferior lobar bronchus gives off the superior segmental bronchus posteriorly. The left inferior lobar bronchus continues inferiorly, giving off an anteromedial basal segmental bronchus and finally the posterior and lateral basal segmental bronchi. These bronchial branches ensure each bronchopulmonary segment of the inferior lobe of the left lung is supplied with an airway.
