    Answer;

    -Murmur

    -Murmur is the sound of blood flowing backward because of a damaged heart valve.

    Explanation;

    -Many heart valve problems are first identified by the presence of a murmur or sound that can be heard when a healthcare provider listens to the heartbeat with a stethoscope.

    -A murmur may sound like a "whooshing" noise of blood flowing under pressure as it moves from one chamber to the next, or it may sound like an extra click when a valve allows back flow. Some murmurs are harmless, and others can indicate an underlying problem with the valve.

    -Murmurs may indicate valve problems including; Stenosis: a narrowing or stiffening of the valve that prevents adequate blood supply from flowing through, Regurgitation: when valves allow blood to flow backward into the chamber, Prolapse: a valve that has improperly closing leaflets and Atresia: when a valve that is improperly formed or missing.
