Anatomy of Blood Supply to Lungs

Pulmonary Circulation

Two Circulations

  • Pulmonary Circulation
  • From Right Ventricle
  • Receives 100% of blood flow
  • Bronchial Circulation
  • From the aorta, intercostal, subclavian, or internal mammary arteries
  • 2% of left ventricular output

Bronchopulmonary Anastamoses

Pulmonary Circulation Cont'd

  • Third of the venous drainage from the bronchial circulation is via the azygos, hemiazygos, and intercostal veins, which returns bronchial venous blood to the right atrium
  • Two-thirds of bronchial capillary blood drains into anastomoses or communicating vessels that empty into the pulmonary veins

Bronchial Circulation

  • Nutrient and gas exchange for conducting airways
