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)
