The heart - image description

The illustration shows the front of the heart and the blood vessels that go into and out of the heart. The major blood vessels that go into or out of the top of the heart are the superior vena cava, the right and left pulmonary arteries, and the aorta. The aorta goes over the top of the heart and is shown coming out from behind the heart at the bottom of the illustration. There are two more blood vessels on each side of the heart and these are the pulmonary veins. At the bottom of the illustration, another blood vessel, the inferior vena cava, is shown going up behind the heart. On the heart muscle itself are smaller blood vessels called coronary arteries.
