Pulmonary vein

The Pulmonary vein (pronunciation: /pʌlˈmɒnəri veɪn/) is a vital component of the circulatory system that carries oxygenated blood from the lungs to the heart.

Etymology

The term "Pulmonary" is derived from the Latin word 'pulmo', meaning 'lung', and "vein" comes from the Old English 'vena', meaning 'blood vessel'.

Function

The primary function of the pulmonary veins is to transport oxygen-rich blood from the lungs to the left atrium of the heart. This oxygenated blood is then pumped by the heart to the rest of the body through the systemic circulation.

Anatomy

There are typically four pulmonary veins, two from each lung. The veins are classified as the right superior, right inferior, left superior, and left inferior pulmonary veins. Each vein carries blood from a corresponding lobe of the lung to the heart.

Related Terms

  • Pulmonary artery: The artery that carries deoxygenated blood from the heart to the lungs.
  • Left atrium: The chamber of the heart that receives oxygenated blood from the pulmonary veins.
  • Systemic circulation: The part of the cardiovascular system which carries oxygenated blood away from the heart to the body, and returns deoxygenated blood back to the heart.
