Web5 stages of the cardiac cycle: Atrial systole - atria contract which power blood into the ventricles. The AV valve opens while the semilunar valves close. Early ventricular systole - ventricle contracts, atria unwind, semilunar valves shut. Late ventricular systole - withdrawal of ventricles, atria unwind, blood powers into the pneumonic ... Web6 dec. 2024 · During each cardiac cycle, the heart contracts (systole), pushing blood out and pumping it around the body; this is followed by a relaxation phase (diastole), during which the heart fills with blood—at the same time, the atria contract, pumping blood into the ventricles through the atrioventricular valves.

Web17 okt. 2024 · The cardiac cycle is the sequence of events that occur in the heart with each beat. In this cycle, blood is pumped out of the heart and oxygen is circulated around the body.
