Describe the normal sounds associated with heart valves

What will be an ideal response?


Two major heart sounds normally can be heard with a stethoscope during the cardiac cycle. The first heart sound is low-pitched, soft, and relatively long; it, sounds like "lub.". The second heart sound has a higher pitch and is shorter and sharper; it sounds like "dup.". Thus, one normally hears "lub-dup-lub-dup-lub-dup . . .". The first heart sound is associated with closure of the AV valves, whereas the second sound is associated with closure of the semilunar valves. Opening of valves does not produce any sound.
