Each of the five image descriptionlung lobes is divided by connective tissue walls (= septa) into anatomical compartments called image descriptionbronchopulmonary segments.

Typically, there are image description10 segments in the right lung and in the left lung. Each segment functions independently and is supplied by its own image descriptiontertiary bronchus (or segmental bronchus) artery, lymph vessels, and autonomic nerves. Thus, if one segment is infected or damaged, others in the same lobe may not be affected.
