A bronchopulmonary segment is a portion of lung supplied by a specific segmental bronchus and its vessels. [1] [2] These arteries branch from the pulmonary and bronchial arteries, and run together through the center of the segment. Veins and lymphatic vessels drain along the edges of the segment.
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 ...

The eparterial bronchus (right superior lobar bronchus) is a branch of the right main bronchus given off about 2.5 cm from the bifurcation of the trachea.This branch supplies the superior lobe of the right lung and is the most superior of all secondary bronchi.
Primary cancers (e.g. bronchial carcinoma, mesothelioma) Secondary cancers (e.g. cancers that originated elsewhere in the body, but have seeded themselves in the lungs) Insufficient surfactant (e.g. respiratory distress syndrome in pre-term babies) . Disorders of the respiratory system are usually treated by a pulmonologist and respiratory ...

The lung bud branches into two lateral outgrowths known as the bronchial buds, one on each side of the trachea. The right and left bronchial buds branch into main (primary), lobar (secondary), segmental (tertiary), and subsegmental bronchi and lead to the development of the lungs . [ 2 ]
