How does the heart produce luv dub sound? |
|
Answer» When the blood moves auricles to ventricles with a huge force and when the heart contracts or relax , that time it produces luv dub sound I want the views of students not the Google. The “ lub” is the first heart sound, commonly termed S1, and is caused by turbulence caused by the closure of mitral and tricuspid valves at the start of systole. The second sound,” dub” or S2, is caused by the closure of aortic and pulmonic valves, marking the end of systole. How?? Force of blood |
