alleryDuring joint diastole of the cardiac cycle, blood flows from
AVentricles into atria through reversed flow
BAtria into pulmonary artery through SAN
CVentricles into aorta through semilunar
DAtria into ventricles through open AV valves
Answer & Solution
Correct answer: D. Atria into ventricles through open AV valves
In joint diastole all chambers relax
the AV valves (tricuspid and bicuspid) are open, allowing passive filling of ventricles from atria via the vena cava and pulmonary veins.
Semilunar valves are closed.
