Solution

1. We will differentiate between lubb and dubb:
LUBB
DUPP
It is the primary coronary heart sound produced through the closure of the bicuspid and tricuspid atrioventricular valves.
It is the second coronary heart sound produced through the closure of pulmonary and aortic semilunar valves.
2. The lubb sound in all fairness loud because of the closure of the atrioventricular valves. 2. The dub sound is softer because of the closure of the aortic and pulmonary valves.
3. The LUBB corresponds to the ventricular systole. 3. The dub sound is softer because of the closure of the aortic and pulmonary valves.
