When the blood passes to the right or left ventricle a valve will close between the atrium and ventricle what sound does it create?
The closure of the atrioventricular valves causes the first heart sound. We hear this as the "lub" of the "lub DUB" heart beat.
What sound does a beating heart make?
lub dub lub dub
What causes the lub-dub sound of your heartbeat?
The 'lub' is the S1 sound. It occurs due to normal closure of the mitral and tricuspid (atrioventricular) valves. With these valves closed, systole commences and blood is actively squeezed from the ventricles. The second sound is the 'dub' or S2 sound. It occurs as the aortic (to LV) and pulmonary (to RV) valves close to prevent backflow from the blood ejected from the ventricles and marks the beginning of diastole (or filling) of the heart.
What is the sound of your beat?
Lub-Dub.

What produces the heart sounds as heard with a stethocope?
The closing of the mitral and tricuspid valves produces the S1 sound, followed by the closing of the aortic and pulmonic valves, which produce the S2 sound. In sequence, it sounds like "lub-DUB, lub-DUB, lub-DUB".
The lub or first heart sound is produced by the closing of?
there are 2 sounds the heart makes. "lub-dub" the first ("lub") is when the atrioventricular valves sclose the second ("dub") is when the semilunar valves close
What causes the lub and dup of the heart?
The lub is caused by the closing of the AV valves. The dup is caused by the semilunar valves closing at the end of systole.
