Name the following:

The phase of the cardiac cycle in which the ventricles get filled with blood from atrium.

Diastole is the phase of the cardiac cycle in which the ventricles get filled with blood from the atrium. Diastole is the period of the cardiac cycle that encompasses ventricular relaxation, passive and active filling of blood into the heart, and the period just prior to ejection.

In the diastole phase, the heart ventricles are relaxed and the heart fills with blood. In the systole phase, the ventricles contract and pump blood out of the heart and to arteries. One cardiac cycle is completed when the heart chambers fill with blood and blood is then pumped out of the heart.
