Adult Heart and Lungs Anatomy

Pulmonary vessels, seen in a dorsal view of the heart and lungs. The lungs have been pulled away from the median line, and a part of the right lung has been cut away to display the air-ducts and bloodvessels. (Testut.)

Historic drawing of the adult lungs showing dorsal view and anatomical size and position with respect to the heart.

  • Each lung - is conical in shape, and presents for examination an apex, a base, three borders, and two surfaces.
  • Left lung - is divided into two lobes, an upper and a lower, by an interlobular fissure.
  • Right lung - is divided into three lobes, superior, middle, and inferior, by two interlobular fissures.
    • Azygos lobe - the right lung upper lobe expands either side of the posterior cardinal. Common condition (0.5% of population) there is also some course variability of the phrenic nerve in the presence of an azygos lobe.
