2. 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.

3. Coronary circulation - Wikipedia

   en.wikipedia.org/wiki/Coronary_circulation

   The anatomy of the veins of the heart is very variable, but generally it is formed by the following veins: heart veins that go into the coronary sinus: the great cardiac vein, the middle cardiac vein, the small cardiac vein, the posterior vein of the left ventricle, and the oblique vein of Marshall.

   The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...

5. 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.

6. Posterior descending artery - Wikipedia

   en.wikipedia.org/wiki/Posterior_descending_artery

   It is typically a branch of the right coronary artery (70%, known as right dominance). Alternately, the PDA can be a branch of the circumflex coronary artery (10%, known as left dominance) which itself is a branch of the left coronary artery. It can also be supplied by an anastomosis of the left and right coronary artery (20%, known as co ...

   The right coronary artery also supplies blood to the atrioventricular node (in about 90% of people) and the sinoatrial node (in about 60% of people). The right coronary artery runs in a groove at the back of the heart and the left anterior descending artery runs in a groove at the front.

8. Coronary sinus - Wikipedia

   Posterior vein of left ventricle (accompanies the left marginal artery, ascends the posterior wall of left ventricle to drain into the coronary sinus); [6] Oblique vein of left atrium. [1] All veins that empty into the coronary sinus except for the oblique vein of the left atrium have valves at their junction with the coronary sinus. [1] The ...
