- The cardiac cycle is the series of contractions in the heart that pressurize different chambers, causing blood to flood in one direction. There are two stages during the cardiac cycle. During diastole, the ventricles relax and fill with blood. The muscles contract during systole, pushing blood through the arteries.

Oct 15, 2024 · What is a cardiac cycle? The sequence of mechanical and electrical events that occurs with every heartbeat. What are the two phases of each heartbeat and what do they represent? Systole- when the heart contracts and pumps blood out of the ventricles. Diastole- when the heart relaxes, and ventricles fill with blood.
