Superior lobe

Superior Lobe

The superior lobe is a section of the lung that is located at the top of each lung. The human body has two superior lobes, one in the right lung and one in the left lung.

Anatomy

Right Lung

The superior lobe of the right lung is one of the three lobes of the right lung. It is separated from the middle lobe by the horizontal fissure and from the inferior lobe by the oblique fissure.

Left Lung

The superior lobe of the left lung is one of the two lobes of the left lung. It is separated from the inferior lobe by the oblique fissure. The left lung does not have a middle lobe.

Function

The superior lobes, like the rest of the lung tissue, are responsible for the exchange of oxygen and carbon dioxide during the process of respiration.

Clinical Significance

Diseases affecting the superior lobe can include pneumonia, lung cancer, and tuberculosis. The superior lobe is often involved in pulmonary embolism due to its position and blood supply.
