Question

Match each description to the correct part of the cardiac cycle: Presure is in the ventricles is greater than pressure in the large ateries, causing blood to flow out into the arteries. Both the AV values and semilunar valves are closed and the ventricles are relaxing. The atria contract, pushing the last ~20% of blood into the ventricles. Both the AV values and semilunar valves are closed and the ventricles are contracting. The heart is at rest and pressure is lowest in the ventricles. Therefore, blood moves from veins, through atria, and into ventricles.
