Valves found between the ventricle and blood vessels?

The correct answer is Semilunar valves.

-Semilunar valves prevent the backflow of blood into the ventricles when the ventricles contract to pump blood into the arteries.

-The pulmonary semilunar valves guard the opening from the right ventricle into the pulmonary trunk, whereas the aortic semilunar valves guard the opening from the left ventricle into the aorta.
