Q

The second stage of the Cardiac cycle: _____ _______, __________ _________ -
Blood empties into the ventricles to equalise the pressure. Blood stops flowing when 70%ish of the blood is in the ventricles. The atria contract, pushing the other 30% into the ventricles.
The atria then relaxes, and the Ventricles contract, closing the AV nodes.

A

Atrial Systole, Ventricular Diastole

Q

The third stage of the Cardiac cycle: _____ _______, __________ _________ - The high pressure in the ventricles cause the SL valves to open, so the blood flows into the aorta and pulmonary arteries.
The ventricles relax, thereby decreasing the pressure, pulling the SL valves closed. The decrease in pressure causes the blood to flow backwards, but the SL valves stop a back flow.

A

Atrial Diastole, Ventricular Systole
