TMC Practice Exam; Courses; Divides the superior and middle lobes. The bronchial tree of the right lung is more vertical and wider than the left, making it more prone to inhaled objects getting trapped. The left lung has two lobes and one fissure; while the right lung has three lobes and two fissures. The lobes are then further subdivided into bronchopulmonary segments; such that the left lung has 9 - 10 segments, while the right lung has 10. Between lobes are interlobar surfaces of lungs which are separated by fissures of the lungs.
Master the lungs anatomy with our study units: Each bronchopulmonary segment is served by corresponding branches of the bronchial tree, along with their own arterial supply. However, The secondary bronchi supply the lobes of the lung, while the segmental branches will deliver oxygen to the respective segments. Superior and inferior

Bronchial tree. From the trachea and main bronchi, the airways further divide into the lobar (ie. secondary) bronchi, and thereafter into the segmental (ie. tertiary) airways. Pulmonary segments are based on this generation of bronchi. A very common variant in lung anatomy is the azygos lobe, where an accessory fissure is present either Each main bronchus further branches into lobar (secondary) bronchi, corresponding to the lobes of each lung (three on the right and two on the left). Bronchoscopy enables visualization of the bronchial tree up to the level of the segmental bronchi and allows clinicians to obtain tissue and fluid samples from more distal airways and the lung
Now, within each lung, the main bronchi divide to form the branches of the bronchial tree, all of which actually belong to the root of the lung. Each main bronchus divides into secondary lobar bronchi, each of which supply a lobe of the lung - so on the right, there are three secondary lobar bronchi: right superior lobar bronchus, right middle Bronchopulmonary segments of left lung by Anatomy.app . Lung histology. Microscopically, the lungs bear a strong resemblance to the structure of an alveolar gland. The lungs contain two parts (also known as trees) - bronchial and alveolar trees. Most of the bronchial tree extends into the lungs, but it does not form the lung parenchyma. It is
