Which statement correctly lists the heart valves by their classification?

Valves are grouped by where they are in the heart and what they separate. The two atrioventricular valves sit between the atria and ventricles, while the two semilunar valves sit between the ventricles and the great arteries. The tricuspid valve and the mitral valve are the AV valves, guarding the flow from atria to ventricles and preventing backflow during ventricular contraction. The aortic valve and the pulmonary valve are the semilunar valves, opening to send blood into the aorta and pulmonary artery and closing to stop backflow when the ventricles relax. This arrangement, with the AV valves on the inlet side and the semilunar valves on the outlet side, is exactly what the statement describes.
