Contour map of the heart, computer artwork. The contours on this map describe the surface shape of the heart, shown here from the front. The large, round region at lower right is the muscular wall enclosing the left ventricle, the smaller area on the left is the surface of the right atrium. At the top, the large vena cava vein (left) and aorta artery (right) can be seen entering the organ. The smaller vessels on the right are the pulmonary veins and arteries, which transport blood between the right side of the heart and the lungs.
