Quizplus · Accepted Answer

The left coronary artery directly stems from the ascending aorta before it branches into the circumflex branch and anterior interventricular branch. This supplies oxygenated blood to the left side of the heart including the left ventricle and left atrium. The right coronary artery stems from the anterior portion of the ascending aorta after it has given rise to the left coronary artery. The great cardiac vein and left coronary vein drain into the coronary sinus, which opens into the right atrium. The right coronary vein drains directly into the right atrium.
