Question : 'Murmurs' are the sound of turbulence as blood flows through the heart; instead of there being two crisp beats of the heart, a whooshing sound can be heard. If a murmur was being caused by dysfunction of the valves between the atria and ventricles, where would you expect to hear the murmur, S1 or S2? S1: (Start of systole): As the ventricles contract, the valves between the atria and the ventricles slam shut
S2: (Start of Diastole): as the ventricles relax, the valves between the ventricles and outside circulation slam shut.

To avoid whiplash, the center of the headrest must be your ears.
