How does arterial pulse is generated by heart?

The arterial pulse is generated by the heart's contractions, specifically during the systole phase of the cardiac cycle. When the heart's ventricles contract, they eject blood into the aorta and pulmonary arteries, creating a surge of blood that travels through the arteries. This surge causes the arterial walls to stretch, resulting in a palpable pulse that can be felt at various points in the body. The pulse reflects the rhythmic nature of the heartbeat and corresponds to each heartbeat.
