There are ten bronchopulmonary segments in the right lung. They are 10 bronchopulmonary segments in the left lung and 8 10 in the left lung.

Surfaces and borders of lungs 3.
Lung segments anatomy. 28 articles feature images from this case. They are separated from adjacent segments by connective tissue septa and are also surgically resectable. Gross anatomy of the lungs.
Left upper lobe apicoposterior segment. The lingula on the left is part of the left upper lobe and is the equivalent. The middle lobe on the right has 2 segments.
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. Hilum and root of lungs 4. Fissures and lobes of lungs 5.
On the inferior surface the lungs are bordered by the diaphragm. In general each lung has 10 segments. Three in the superior lobe two in the middle lobe and five in the inferior lobe.
Each segment has its own vascular inflow outflow and biliary drainage. The upper lobes contains 3 segments the middle lobe lingula 2 and the lower lobes 5. The couinaud classification of liver anatomy divides the liver into eight functionally indepedent segments.
Functionally the lung is divided into a series of bronchopulmonary segments. Nerve supply of lungs 11. Right upper lobe apical segment.
Lymphatics of lungs 10. In the centre of each segment there is a branch of the portal vein hepatic artery and bile duct. Histopathology of alveoli 7.
Each bronchopulmonary segment is served by corresponding branches of the bronchial tree along with their own arterial supply. The bronchopulmonary segments are the largest subdivision of a lobe. Gross anatomy of lungs 2.
Medial and lateral easy to remember m iddle l obe. Blood supply of lungs 9. Right upper lobe posterior segment.
With this basic symmetric anatomy shared between the lungs there are a few differences that can be described. The diaphragm is the flat dome shaped muscle located at the base of the lungs and thoracic cavity. The lungs can be further subdivided into bronchopulmonary segments.
Right upper lobe anterior segment. Bilaterally the upper lobes have apical posterior and anterior segments and the lower lobes superior apical and 4 basal segments anterior medial posterior and lateral. Anatomy of the bronchopulmonary segments.
There are ten such segments located within the right lung and roughly 8 9 on the left side as some of the segments may fuse together. The lungs are pyramid shaped paired organs that are connected to the trachea by the right and left bronchi.
