Lung Anatomy 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. Each segment has its own vascular inflow outflow and biliary drainage.

They are separated from adjacent segments by connective tissue septa and are also surgically resectable.

Lung anatomy segments. Functionally the lung is divided into a series of bronchopulmonary segments. Each bronchopulmonary segment is served by corresponding branches of the bronchial tree along with their own arterial supply. The lingula on the left is part of the left upper lobe and is the equivalent.

Anatomy of the bronchopulmonary segments. The lungs can be further subdivided into bronchopulmonary segments. The couinaud classification of liver anatomy divides the liver into eight functionally indepedent segments.

Medial and lateral easy to remember m iddle l obe. With this basic symmetric anatomy shared between the lungs there are a few differences that can be described. In general each lung has 10 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 extrathoracic superior airway which includes the supraglottic glottic and infraglottic regions the intrathoracic inferior airway which includes the trache. The anatomy of the respiratory system can be divided into 2 major parts airway anatomy and lung anatomy.

The middle lobe on the right has 2 segments. The upper lobes contains 3 segments the middle lobe lingula 2 and the lower lobes 5. Airway anatomy can be further subdivided into the following 2 segments.

The bronchopulmonary segments are the largest subdivision of a lobe. In the centre of each segment there is a branch of the portal vein hepatic artery and bile duct. They are 10 bronchopulmonary segments in the left lung and 8 10 in the left lung.
