What are heart sounds? How are they produced?

उत्तर
The rhythmic closure and opening of the valves cause the sound of the heart. When the closure of the tricuspid and bicuspid valves after the beginning of ventricular systole, the sound ‘LUBB’ is produced. When the closure of the semilunar valve at the end of ventricular systole, the sound ‘DUPP’ is produced.
