Murmurs in heart sounds are caused by

Explanation:
Murmurs arise from turbulent blood flow, meaning the movement of blood through the heart or great vessels isn’t smooth. When a valve is narrowed or leaky, or when an abnormal connection exists, blood speeds up and swirls, producing vibrations that you hear as an extra sound with a stethoscope. Normal heart sounds (S1 and S2) come from valve closures and are not murmurs, because they result from regular, laminar flow rather than turbulence. So the key mechanism behind murmurs is turbulent blood flow.
