What is the term for blood being pumped from the ventricles to the aorta and pulmonary artery?

The term for blood being pumped from the ventricles to the aorta and pulmonary artery is systole. During systole, the ventricles contract, generating the pressure necessary to eject blood into the systemic circulation through the aorta and into the pulmonary circulation through the pulmonary artery. This phase of the cardiac cycle is crucial as it ensures that oxygen-rich blood is delivered to the body and deoxygenated blood is sent to the lungs for oxygenation.

Diastole refers to the relaxation phase of the heart when the chambers fill with blood. The cardiac cycle encompasses both systole and diastole, representing the complete sequence of events during one heartbeat. Heart rate is a measure of how many times the heart beats in one minute, but it does not specifically refer to the action of blood being pumped from the ventricles. Hence, the concept of systole is at the core of understanding how blood is actively circulated from the heart to the rest of the body and lungs.
