Vibrations associated with the closing of the semilunar valves.
S1 S2 are heart sounds. The S1 sound occurs at the beginning of systole (end of diastole). The S2 sound occurs at the beginning of Diastole (end of systole).
closing of the semilunar valves at the start of diastole
diastole
Diastole is when the muscles of the atria and ventricles relax and blood flows into the heart.Ventricular diastole is when the muscles of the ventricles relax and blood flows into the heart. N.B It is called ventricular diastole and not ventrical diastole.
diastole
I believe that is called diastole, in contrast to systole, the contraction of the heart muscles.
Diastole is when the artery is pushing the blood around the body
Atrial refers to the top portion of the heart and diastole is when the heart is at rest. Atrial diastole would be when the top portion of the heart is not beating.
The relaxing phase of the cardiac cycle is called diastole. During diastole, the heart chambers (atria and ventricles) relax, allowing them to fill with blood. This is followed by the contracting phase called systole.
