Again, when all the blood is in the left ventricle, the bicuspid valve slams shut to prevent blood from flowing backwards. WebThe atrioventricular valves are the mitral valve, and the tricuspid valve, which are situated between the atria and the ventricles, and prevent backflow from the ventricles into the atria during systole. They are anchored to the walls of the ventricles by chordae tendineae, which prevent them from inverting.

WebMay 8, 2024 · The four valves in order of circulation are: Tricuspid Valve. Has three leaflets or cusps. Separates the top right chamber (right atrium) from the bottom right chamber (right ventricle). Opens to allow blood to flow from the right atrium to the right ventricle. Prevents the back flow of blood from the right ventricle to the right atrium. WebThe names bi- and tricuspid are derived from the number of cusps or flaps that make up the valve.
