The cardiac ventricles are the two lower chambers of the heart's four chambers. They are larger and more narrowed than the atria.

Do any of the four chambers of the heart empty fully?
No, the chambers of the heart do not empty completely with each heartbeat. The ventricles, which are the lower chambers, eject a significant portion of their blood during contraction, but some blood remains to maintain pressure and ensure continuous circulation. This incomplete emptying helps the heart function more efficiently and prepares for the next cycle of filling and contraction.
Why is the walls of the lower chambers in the heart thicker than the walls of the upper chambers?
Because the net weight of the fluid in the blood is bigger, because the bigger size of the lower chambers (ventricles) allows more blood to accumulate in there, thus causing the need for thicker walls
