ABSTRACT
The heart sounds are an audible expression of the heart valves closing. Their physiological function is always unidirectional, allowing the proper blood flow through the cardiovascular circuit. Listening – by auscultation- to the specific chest areas allows the identification of these sounds and nuances in the five auscultation areas. There are sounds that are not produced by the closing of the valves; to mention a few, we can find the so-called puffs and Korotkoff sounds, both produced by interrupting the natural flow of blood flow (laminar flow) that becomes a turbulent flow whenever there is a reduction of the radius of the conduits through which this the blood circulates.REFERENCES
