(From Wikipedia, the free Encyclopedia)
There are four valves of the heart:
The chordae teninae are attached to papillary muscles that cause tension to better hold the valve. They have no effect on the opening at shutting though. This is caused entirely by a pressure difference on each side of the valve.
AV valves
These are large, multicusped valves that prevent backflow from the ventricles into the atria during systole. They are anchored to the wall of the ventricle by chordae tendinae, that prevent the valve from inverting.Mitral valve
Also known as the bicuspid valve, the mitral valve gets its name from the resemblance to a bishop's mitre (a type of hat). It prevents blood flowing from the left ventricle into the left atrium. As it is on the left side of the heart, in must cope with a lot of strain and pressure, this is while it is madeof only two cusps, as there is less to go wrong.
Tricuspid valve
It is on the right side of the heart, and prevents flow from the right ventricle to the right atrium. Being the first valve after the venae cavae, and thus the whole venous system, it is the most common valve to be infected (endocarditis) in IV drug users.Semilunar valves
These are positioned on the pulmonary artery and the aorta. This valves to not have chordae tendinae, but are more similar to valves in veins.
Aortic valve
Stops blood coming back from the aorta into the left ventricle during diastole.
Pulmonary valve
Prevents blood flow back from the pulmonary trunk to the right ventricle.Pathology of the valves
Artificial heart valves
