  2. Coronary circulation - Wikipedia

    en.wikipedia.org/wiki/Coronary_circulation

    Coronary circulation is the circulation of blood in the arteries and veins that supply the heart muscle (myocardium). Coronary arteries supply oxygenated blood to the heart muscle. Cardiac veins then drain away the blood after it has been deoxygenated.

  3. Coronary arteries - Wikipedia

    en.wikipedia.org/wiki/Coronary_arteries

    The coronary arteries are the arterial blood vessels of coronary circulation, which transport oxygenated blood to the heart muscle. The heart requires a continuous supply of oxygen to function and survive, much like any other tissue or organ of the body. [1] The coronary arteries wrap around the entire heart.

  4. Circumflex branch of left coronary artery - Wikipedia

    en.wikipedia.org/wiki/Circumflex_branch_of_left...

    The circumflex artery curves to the left around the heart within the coronary sulcus, giving rise to one or more left marginal arteries (also called obtuse marginal branches) as it curves toward the posterior surface of the heart. It helps form the posterior left ventricular branch or posterolateral artery.

  6. Left coronary artery - Wikipedia

    en.wikipedia.org/wiki/Left_coronary_artery

    [citation needed] The left coronary artery typically runs for 10–25 mm, then bifurcates into the left anterior descending artery, and the left circumflex artery. [ 1 ] The part that is between the aorta and the bifurcation only is known as the left main artery (LM), while the term "LCA" might refer to just the left main, or to the left main ...

  7. Right coronary artery - Wikipedia

    en.wikipedia.org/wiki/Right_coronary_artery

    The RCA also supplies the SA nodal artery in 60% of people. The other 40% of the time, the SA nodal artery is supplied by the left circumflex artery. [citation needed] Although rare, several anomalous courses of the right coronary artery have been described including origin from the left aortic sinus. [9]

  8. Circulatory system - Wikipedia

    en.wikipedia.org/wiki/Circulatory_system

    The coronary circulation begins near the origin of the aorta by two coronary arteries: the right coronary artery and the left coronary artery. After nourishing the heart muscle, blood returns through the coronary veins into the coronary sinus and from this one into the right atrium.

  9. Left anterior descending artery - Wikipedia

    en.wikipedia.org/.../Left_anterior_descending_artery

    Widow maker is an alternative name for the anterior interventricular branch of the left coronary artery. [9] [3] The name widow maker may also apply to the left coronary artery [10] or severe occlusions to that artery. [11] [12] This term is used because the left main coronary and/or the left anterior descending supply blood to large areas of ...
