There are four heart valves—mitral, aortic, tricuspid, and pulmonary. Normally functioning valves ensure that blood flows in one direction. When dysfunction of the heart valves occurs, the valves may become narrow (valvular stenosis) or may leak (valvular regurgitation) allowing blood to flow backwards. This can lead to chronic heart problems including heart failure, shortness of breath and chest pain, or enlargement of the heart chambers.
Mitral Valve- helps blood return to the heart from the lungs and separates the left atrium and left ventricle
Aortic Valve- helps blood move from the left ventricle into the aorta so it can travel out to the all the parts of the body.
Tricuspid Valve- helps blood returning from the body to move from the right atrium to the right ventricle
Pulmonary Valve- helps to move blood from the right ventricle into the pulmonary artery so it can travel to the lungs to be oxygenated
