What causes the heart sound LUBB and dub?

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.

Mainly when people are nervous then too it happens.
