An incompetent valve allows backflow of blood.
What do valves do in your heart?
valves prevent the backflow of blood.
Which heart valves prevent backflow into the ventricles?
The semilunar valves prevent backflow into the ventricles. The pulmonary semilunar valve prevents backflow in the right ventricle, and the aortic semilunar valve prevents backflow of blood in the left ventricle.
Do atrioventricular vales prevent backflow into the heart?
yes, they get it back by pumping blood to the 4 parts of your heart. when you inhale, it makes rich blood when you exhale it takes out poor blood which turns into carbon dioxide.

Compare and contrast the hydraulic system to the human heart?
well their are valves in the human heart, and they control the amount of blood entering the heart, and the backflow of it aswell
