As a cardiac physiologist with a focus on the mechanics of the heart, I can explain the concept of ventricular diastole. Ventricular diastole is a phase of the cardiac cycle during which the ventricles, the lower chambers of the heart, are in a state of relaxation and are filling with blood. This period follows ventricular systole, the phase where the ventricles contract to pump blood out to the body and lungs. During ventricular diastole, the pressure inside the ventricles decreases, allowing blood to flow in from the atria, which are the upper chambers of the heart. The process of ventricular diastole is crucial for the heart's ability to maintain a continuous and efficient blood circulation throughout the body. read more >>

Ventricular diastole is the period during which the two ventricles are relaxing from the contortions of contraction, then dilating and filling; atrial diastole is the period during which the two atria likewise are relaxing, dilating, and filling.read more >>
