Heart Valves
Heart ValvesFour cardiac valves help to direct flow through the heart. Heart valves cause blood to flow only in the desired direction. If a heart without these valves were to contract, it would compress the blood, causing it to flow both backward and forward (upstream and downstream). Instead, under normal physiological conditions, heart valves act as check valves to prevent blood from flowing in the reverse direction. In addition, heart valves remain closed until the pressure behind the valve is large enough to cause blood to move forward.Each human heart has two atrioventricular (AV) valves which are located between the atria and the ventricles. The tricuspid valve is the valve between the right atrium and the right ventricle. The mitral valve is the valve between the left a…
