During the Late Stages of Ventricular Diastole, the ________

Question

During the late stages of ventricular diastole, the ________.
A) atria are contracting
B) AV valves are closed
C) ventricles are contracting
D) pressure in the ventricles does not change
E) ventricles are filling

Accepted Answer

During the late stages of ventricular diastole, the ventricles are filling with blood. This is because the AV valves are open and the pressure in the ventricles is lower than that in the atria, allowing blood to flow from the atria into the ventricles. Both atria and ventricles are relaxed at this point, and there is no contraction happening yet.
