There are ten bronchopulmonary segments in the right lung: three in the superior lobe, two in the middle lobe, and five in the inferior lobe. Some of the segments may fuse in the left lung to form usually eight to nine segments (four to five in the upper lobe and four to five in the lower lobe.
A bronchus (/ ˈ b r ɒ ŋ k ə s / BRONG-kəs; pl.: bronchi, / ˈ b r ɒ ŋ k aɪ / BRONG-ky) is a passage or airway in the lower respiratory tract that conducts air into the lungs.The first or primary bronchi to branch from the trachea at the carina are the right main bronchus and the left main bronchus.
The lobar bronchi branch into tertiary bronchi also known as segmental bronchi and these supply air to the further divisions of the lobes known as bronchopulmonary segments. Each bronchopulmonary segment has its own (segmental) bronchus and arterial supply. [8] Segments for the left and right lung are shown in the table. [5]
The right lung has three lobes – upper, middle, and lower (or superior, middle, and inferior), and the left lung has two – upper and lower (or superior and inferior), plus a small tongue-shaped portion of the upper lobe known as the lingula. Each lobe is further divided up into segments called bronchopulmonary segments. Each lung has a ...
This methodology provided a permanent specimen which could be measured, photographed, or even colorfully painted to delineate the bronchopulmonary segments. Bronchial artery casting techniques, modified and refined by Liebow and his colleagues, demonstrated the importance of dual circulation in the lung, particularly in inflammatory diseases of ...
Pulmonary hypoplasia is an incomplete development of the lungs, resulting in an abnormally low number or small size of bronchopulmonary segments or alveoli.A congenital malformation, most often occurs secondary to other fetal abnormalities that interfere with normal development of the lungs.
Postural drainage is used to treat any condition that causes the build-up of secretions in bronchopulmonary segments. These include: bronchiectasis [2] [3] lung abscesses [2] [3] cystic fibrosis [3] atelectasis [3] chronic obstructive pulmonary disease (COPD) [3] pneumonia [3] postoperative lung damage (after some thoracic surgery) [3] COVID-19 [4]
