Question

why are the valves location not same with the auscultatory areas

Answer 1

It has to do with how the sound of closure of valves are transmitted if im not wrong @Abhisar but i dont exactly know how to explain it v_v

Answer 2

Yes, what we hear actually during S1 is the sound produced by turbulence caused by the closure of mitral and tricuspid valves at the start of systole. S2, is caused by the closure of aortic and pulmonic valves (semilunar valves), marking the end of systole. So it's NOT THE VALVES MAKING SOUND but the turbulent flow of blood and hence the auscultatory areas do not match exactly with the location of valves.

Answer 3

Generally, auscultatory point for S1 is posterior to cuspid valves (towards apex of heart) and auscultatory point for S2 is anterior to semilunar valves

Answer 4

@inkyvoyd

Answer 5

& turbulence is created because of valves

Answer 6

well, not solely that tho

Answer 7

Yeah, mostly. It obstructs the blood flow hence creating turbulence.

Answer 8

In fact, sounds and murmurs in cardiac/circulatory system are mostly associated with turbulence which is created whenever blood is unable to flow freely and has to face some kind of resistance.

Answer 9

Yep :3

Answer 10

Got this answered already but thanks @Abhisar @Somy

Answer 11

auscultatory areas are not the same with the anatomic location of the valves because the valves' locations are too close to each other, that when a stethoscope is places on top it would be hard to distinguish which valve is exactly being listened to. Hence the sites of auscultation are placed adjacent to the location of the valves.
