    My only comment is that the sound that is heard during auscultation is not actually due to the closure of the valves, but what we are hearing is the vibration of blood along the walls and major vessels of the heart. From what my professor taught us, the actual closure of the valve leaflets causes almost no sound. Many thanks for all your videos!
