The shallow depression on the external surface of the heart between the left and right ventricles is called the interventricular sulcus. The coronary sinus is a large vein on the back of the heart that receives blood from the heart muscle. The interventricular septum is the wall that separates the left and right ventricles. The coronary sulcus is a groove that encircles the heart and marks the boundary between the atria and ventricles. The left atrium is the upper left chamber of the heart that receives blood from the lungs.
