  2. Bronchial veins - Wikipedia

    en.wikipedia.org/wiki/Bronchial_veins

    The right side drains into the azygos vein, while the left side drains into the left superior intercostal vein or the accessory hemiazygos vein. Bronchial veins are thereby part of the bronchial circulation, carrying waste products away from the cells that constitute the lungs. The bronchial veins are counterparts to the bronchial arteries.

  3. Bronchial circulation - Wikipedia

    en.wikipedia.org/wiki/Bronchial_circulation

    Bronchial veins drain venous blood from the large main bronchi into the azygous vein, and ultimately the right atrium. Venous blood from the bronchi inside the lungs drains into the pulmonary veins and empties into the left atrium; since this blood never went through a capillary bed it was never oxygenated and so provides a small amount of ...

  4. Renal circulation - Wikipedia

    en.wikipedia.org/wiki/Renal_circulation

    After filtration occurs, the blood moves through a small network of venules that converge into interlobular veins. As with the arteriole distribution, the veins follow the same pattern: the interlobular provide blood to the arcuate veins then back to the interlobar veins, which come to form the renal vein exiting the kidney for transfusion for ...

  5. Vein - Wikipedia

    en.wikipedia.org/wiki/Vein

    In the bronchial circulation that supplies blood to the lung tissues, bronchial veins drain venous blood from the large main bronchi into the azygous vein, and ultimately the right atrium. Venous blood from the bronchi inside the lungs drains into the pulmonary veins and empties into the left atrium; since this blood never went through a ...

  6. Pulmonary vein - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_vein

    There are four main pulmonary veins, two from each lung – an inferior and a superior main vein, emerging from each hilum. The main pulmonary veins receive blood from three or four feeding veins in each lung, and drain into the left atrium. The peripheral feeding veins do not follow the bronchial tree.

  7. Circulatory system - Wikipedia

    en.wikipedia.org/wiki/Circulatory_system

    The pulmonary circulation is the part of the circulatory system in which oxygen-depleted blood is pumped away from the heart, via the pulmonary artery, to the lungs and returned, oxygenated, to the heart via the pulmonary vein. Oxygen-deprived blood from the superior and inferior vena cava enters the right atrium of the heart and flows through ...

  8. Pulmonary circulation - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_circulation

    The right pulmonary artery passes dorsally to the ascending aorta, while the left pulmonary artery passes ventrally to the descending aorta. De-oxygenated blood leaves the heart, goes to the lungs, and then enters back into the heart. [2] De-oxygenated blood leaves through the right ventricle through the pulmonary artery. [2]

  9. Renal vein - Wikipedia

    en.wikipedia.org/wiki/Renal_vein

    The renal veins in the renal circulation, are large-calibre [1] veins that drain blood filtered by the kidneys into the inferior vena cava. There is one renal vein draining each kidney. [citation needed] Each renal vein is formed by the convergence of the interlobar veins of one kidney. [2]
