Question

During the period of ventricular filling:

A) blood flows passively through the atria and the open AV valves.
B) pressure in the heart is at its peak.
C) the aortic valve is open.
D) the atria remain in diastole.

Answer 1

During the period of ventricular filling, blood flows passively through the atria and the open AV valves.

Step-by-step explanation:

During the period of ventricular filling, blood flows passively through the atria and the open AV valves. The atria receive blood from the venae cavae and the pulmonary veins. The tricuspid and mitral valves are open, allowing blood to flow from the atria into the ventricles.
