   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 .

3. Coronary arteries - Wikipedia

   The right coronary artery (RCA) originates within the right cusp of the aortic valve. It travels down the right coronary sulcus, towards the crux of the heart. The RCA primarily branches into the right marginal arteries, and, in 67% of individuals, gives place to the posterior descending artery. [4]

   The right marginal branch is the largest branch to split off from the right coronary artery. [1] [2] It often anastomoses with the nearby parallel posterior interventricular artery, which itself is usually a continuation of the right coronary artery. [3]

   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 ...

6. Coronary circulation - Wikipedia

   en.wikipedia.org/wiki/Coronary_circulation

   The right coronary artery proceeds along the coronary sulcus and distributes blood to the right atrium, portions of both ventricles, and the heart conduction system. Normally, one or more marginal arteries arise from the right coronary artery inferior to the right atrium. The marginal arteries supply blood to the superficial portions of the ...

7. 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 sulcus begins anteriorly and superiorly on the sternocostal surface of the heart. Its position is marked by the location of the right coronary artery, and small cardiac vein. The right coronary sulcus separates the right atrium and its atrial appendage from the right ventricle inferiorly. The right coronary sulcus then passes ...
