The characteristic "lub-dup" sounds are associated with closing of heart valves.

The first sound (lub) occurs as atrioventricular valves close and signifies beginning of systole (contraction)
The second sound (dup) occurs when semilunar valves close at the beginning of ventricular diastole (relaxation)

Thanks to Debra Copeland, for providing fetal heart beat for public use.
