Correct answers:
- Atria push blood into the ventricles.
- Ventricles push blood out of the heart.
Explanation: Venous blood first enters the atria, which contract to fill the ventricles; the ventricles then contract to eject blood out of the heart. Heart valves ensure one-way flow (not two-way), and atria and ventricles contract sequentially (atria first).
