Heart Sounds. Heart sounds are generated by the turbulance created by blood flowing through the heart, specifically when the heart valves close. Normal heart sounds can be characterized by a lub dub that occurs with a heart beat. The first heart sound (lub) occurs when the atrioventricular (AV) valves close and the second heart sound (dub) is heard when the semilunar valves close.
They open to allow blood to move in one direction and close to keep blood from backing up. The first sound results from closure of the mitral and tricuspid valves, which separate the upper and lower chambers of the heart. The second sound occurs as a result of closure of the pulmonic and aortic valves. Blood travels across these valves on its way to the lungs and heart.
