+Diastole is the heart's period of rest and renewal, when its chambers, notably the [Ventricle](/wiki/ventricle)s, relax and fill with [Blood](/wiki/blood). This essential phase allows the heart to replenish itself before the vigorous contraction of systole, ensuring efficient circulation throughout the body.
