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

First sound (lub) occurs as atrioventricular valves close and signifies beginning of systole (contraction).
Second sound (dup) occurs when semilunar valves close at the beginning of ventricular diastole (relaxation).

There is both a tutorial and development information page for cardiac valve development.

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