Respuesta :
The Passive filling of the ventricles through the open valves occurs at the beginning of the cardiac cycle while the ventricles are in Diastole.
In the cardiac cycle, what is a passive filling?
The atrioventricular valves open when the difference between the pressures in the atria and ventricles falls below a certain threshold. The left heart's mitral valve opens to show this when the left ventricle's pressure falls below that of the left atrium. The ventricle now starts to passively fill.
How do you define diastole?
When the heart muscle relaxes, it is in diastole. Blood flows into the heart's chambers as the heart slows down, which lowers blood pressure.
