Which heart phase involves the chambers pumping blood?

The phase of the heart cycle that involves the chambers actively pumping blood is referred to as systole. During systole, both the atria and the ventricles contract, which forces blood out of the heart. The ventricles contract to propel blood into the aorta and pulmonary arteries, while the atria contract to push blood into the ventricles before their contraction.

This phase is critical for circulation, as it ensures that oxygenated blood is delivered to the body and deoxygenated blood is sent to the lungs for oxygenation. The efficiency and timing of systolic contractions are vital for maintaining adequate blood pressure and flow throughout the cardiovascular system. Understanding this phase is essential for a cardiographic technician, as it directly relates to how the heart functions to support bodily needs through its pumping action.
