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.
