During the period of ventricular filling ________.
A) the aortic and pulmonary semilunar valves are open
B) blood flows mostly passively through the atria and the open atrioventricular (AV) valves into the ventricles
C) the atria remain in diastole
D) pressure in the heart is at its peak

Question

Quizplus · Accepted Answer

During ventricular filling, the atrioventricular valves are open and blood flows mostly passively from the atria to the ventricles. The semilunar valves are closed during this phase. The atria are in diastole, while the ventricles are in late diastole. Pressure in the heart is low during this phase as the chambers are relaxed and filling up with blood.
