what diastole
passive filling of ventricles followed by contraction of the atria
What does S1 sound represent?
the closure of the AV valves.
what is the S2 sound?
the closure of the aortic and pulmonic valves
What is the S3 sound?
diastolic motion and rapid filling of the ventricles in early diastole
What is the S4 sound?
atrial contraction in late diastole to enure the ejection of remaining blood.
