 Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut. In cardiac auscultation, an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding the condition of the heart.The illustrated guide below provides a  details discussion of various heart sounds, murmurs and lung sounds as they relate to the anatomy, physiology, pathology, pathophysiology and diagnosis of these common cardiovascular and pulmonary diseases.
