Lung Anatomy Segments

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.

Functionally the lung is divided into a series of bronchopulmonary segments.

Lung anatomy segments. The lingula on the left is part of the left upper lobe and is the equivalent. The lungs can be further subdivided into bronchopulmonary segments. The middle lobe on the right has 2 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. They are separated from adjacent segments by connective tissue septa and are also surgically resectable. In general each lung has 10 segments.

Each bronchopulmonary segment is served by corresponding branches of the bronchial tree along with their own arterial supply. Anatomy of the bronchopulmonary segments. The extrathoracic superior airway which includes the supraglottic glottic and infraglottic regions the intrathoracic inferior airway which includes the trache.

They are 10 bronchopulmonary segments in the left lung and 8 10 in the left lung. Medial and lateral easy to remember m iddle l obe. In the centre of each segment there is a branch of the portal vein hepatic artery and bile duct.

The bronchopulmonary segments are the largest subdivision of a lobe. Airway anatomy can be further subdivided into the following 2 segments. 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.

With this basic symmetric anatomy shared between the lungs there are a few differences that can be described. The couinaud classification of liver anatomy divides the liver into eight functionally indepedent segments. The anatomy of the respiratory system can be divided into 2 major parts airway anatomy and lung anatomy.
