The Superior Pulmonary Vein is a major blood vessel in the human body. It is one of the two pulmonary veins that carry oxygenated blood from the lungs to the heart. The superior pulmonary vein is responsible for draining the upper lobes of the lungs.

Structure

The superior pulmonary vein is located in the thoracic cavity, and it is formed by the union of several smaller veins that drain the upper lobes of the lungs. It enters the left atrium of the heart at the posterior part, above the inferior pulmonary vein.

Function

The primary function of the superior pulmonary vein is to transport oxygenated blood from the lungs to the heart. This is a crucial part of the pulmonary circulation, which is responsible for oxygenating the blood.

Clinical significance

Abnormalities or diseases affecting the superior pulmonary vein can lead to serious health problems, such as pulmonary hypertension and pulmonary embolism. It is also a common site for the formation of blood clots.
