Left lung

Other Terms: Pulmo sinister, linker Lungenflügel, Pulmón izquierdo, Polmone di sinistra


The left lung is divided into two lobes, the upper and the lower, by the oblique fissure. On the mediastinal surface, is a well-marked furrow produced by the aortic arch, and running upward from this toward the apex is a groove accommodating the left subclavian artery. A slight impression in front of the latter and close to the margin of the lung is the left brachiocephalic vein. Behind the hilum and pulmonary ligament is a vertical furrow produced by the descending aorta, In front of this, near the base of the lung, the lower part of the esophagus causes a shallow impression. The left lung is smaller than the right because of the room needed for the heart.
