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.

Atrioventricular valves

Semilunar valves

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