    Transcript

    00:01 So next, let's talk about heart sounds.

    00:05 When you listen to the heart, you hear two sounds.

    00:10 We refer to these sounds as the "lub-dub" and this is associated with the closing of those valves.

    00:18 So the first sound or the "lub" is the closing of the AV valves at the beginning of ventricular systole.

    00:27 The second sound that you here or the "dub" is the closing of the semilunar valves at the beginning of ventricular diastole.

    00:37 and the pause between the two sounds indicates the relaxation of the heart.

    00:45 So the mitral valve closes slightly before the tricuspid and the aortic valve closes slightly before the pulmonary valve.

    00:55 So the differences allow for auscultation or the listening of the heart of each valve when a stethoscope is placed in four different regions.

    01:07 So we can place the stethoscope in specific places on the body in order to listen to the aortic valve, the tricuspid valve, the pulmonary valve and the mitral valve.
