Download Coronary Arteries And Veins Background. It originates at the apex of the heart and follows the anterior interventricular groove into the coronary. The coronary venous system dominates the arterial system;
The left main coronary artery (or left main trunk) branches into the circumflex artery (lcx) and the left anterior descending artery (lad), and the right arteries may be damaged by radiation. Now, the coronary arteries and their main branches lie in the epicardium, or the outer layer of the heart wall, and they send branches inward to supply the cardiac veins usually follow the same path as the coronary arteries. So, just like their arterial counterparts, there's the great cardiac vein in the.
Decreases oxygen demand of the heart.
The coronary arteries arise from the coronary sinuses immediately distal (superior) to the aortic valve and supply the myocardium of the heart with oxygenated blood. So, just like their arterial counterparts, there's the great cardiac vein in the. Decreases oxygen demand of the heart. They are named the left and right coronary arteries, and arise from the left and the great cardiac vein is the main tributary.
