  2. Pulmonary vein - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_vein

    Pulmonary vein anatomy is highly variable among atrial fibrillation patients. [5] Pulmonary vein isolation by transcatheter ablation can restore sinus rhythm . [ 4 ] As atrial fibrillation becomes more persistent, the junction between the pulmonary veins and the left atrium becomes less of an initiator and the left atrium becomes an independent ...

  3. Pulmonary circulation - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_circulation

    The pulmonary circulation is a division of the circulatory system in all vertebrates. The circuit begins with deoxygenated blood returned from the body to the right atrium of the heart where it is pumped out from the right ventricle to the lungs .

  4. Circulatory system - Wikipedia

    en.wikipedia.org/wiki/Circulatory_system

    In vertebrates, the circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the body. [ 1 ] [ 2 ] It includes the cardiovascular system , or vascular system , that consists of the heart and blood vessels (from Greek kardia meaning heart , and Latin vascula meaning vessels ).

  6. Blood vessel - Wikipedia

    en.wikipedia.org/wiki/Blood_vessel

    The circulatory system uses the channel of blood vessels to deliver blood to all parts of the body. This is a result of the left and right sides of the heart working together to allow blood to flow continuously to the lungs and other parts of the body. Oxygen-poor blood enters the right side of the heart through two large veins.

    structures of the cardiovascular system, including the heart and great vessels, which include the thoracic aorta, the pulmonary artery and all its branches, the superior and inferior vena cava, the pulmonary veins, and the azygos vein; structures of the respiratory system, including the diaphragm, trachea, bronchi and lungs [1]

  9. Heart - Wikipedia

    en.wikipedia.org/wiki/Heart

    The pulmonary trunk divides into pulmonary arteries and progressively smaller arteries throughout the lungs, until it reaches capillaries. As these pass by alveoli carbon dioxide is exchanged for oxygen. This happens through the passive process of diffusion. In the left heart, oxygenated blood is returned to the left atrium via the pulmonary veins.
