Download Lecture Overview
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.
