The closure of which valves causes the sounds “lub” and “dup”?
The closing of the
and
valves produces the “lub” sound. The closing of the
valves produces the “dup” sound.

The atrioventricular (AV) valves consists of the tricuspid valve and the bicuspid/mitral valve- When the AV valves open they are responsible for the “lub sound”

The semilunar (SL) valves consist of the aortic valve and the pulmonic valve- When the SL valves close they cause the “dup” sound.
