In the blood supply of the heart, the right coronary artery (RCA) is an artery originating above the right cusp of the aortic valve, at the right aortic sinus in the heart. [ 1 ] [ 2 ] It travels down the right coronary sulcus , towards the crux of the heart .
The coronary arteries are mainly composed of the left and right coronary arteries, both of which give off several branches, as shown in the 'coronary artery flow' figure. Coronary artery flow Aorta. Left coronary artery. Left anterior descending artery; Left circumflex artery; Posterior descending artery; Ramus or intermediate artery; Right ...

The circumflex artery arises from the left coronary artery and follows the coronary sulcus to the left. Eventually, it will fuse with the small branches of the right coronary artery. The larger left anterior descending artery (LAD), is the second major branch arising from the left coronary artery. It follows the anterior interventricular sulcus ...
The blood supply of the AV node is from the atrioventricular nodal branch. The origin of this artery is most commonly (80–90% of hearts) a branch of the right coronary artery, with the remainder originating from the left circumflex artery. [4] [5] [6] This is associated with the dominance of the coronary artery

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 ...
distal posterolateral branch from the right coronary artery in around 2%. [1] distal right coronary artery in around 10%. [1] right posterior interventricular artery in around 7%. [1] distal circumflex branch of left coronary artery in around 4%. [1] The right coronary artery supplies the atrioventricular node in around 90% of people. [1] [2]
