The tricuspid valve connects the right atrium with the right ventricle. The semilunar valves allow the blood to flow out of the heart into the 2 main arteries (aorta and pulmonary artery). They prevent blood from returning to the heart. The top of the heart connects to a few large blood vessels. The largest of these is the aorta, or main artery, which carries nutrient-rich blood away from the heart. Another important vessel is the pulmonary artery which connects the heart with the lungs as part of the pulmonary circulation system. The two largest veins that carry blood into the heart are the superior vena cava and the inferior vena cava.
