Quizplus · Accepted Answer

Each primary bronchus branches into secondary bronchi, which then branch into tertiary bronchi. Each tertiary bronchus supplies a bronchopulmonary segment, which corresponds to a specific lobe of the lung. Therefore, the portion of the bronchial tree that supplies each lobe of the lungs is the secondary bronchi.
