10+ Cardiac Cycle Phases Diagram. The cardiac cycle is the series of contractions in the heart that pressurize different chambers, causing blood to flood in one direction. Click now to learn more at kenhub!
Cardiac cycle the cardiac muscles of the heart contract and relax in a rhythmic cycle. Want to learn more about it? Each stage in the cardiac cycle contains important steps.
A cardiac cycle includes the mechanical and electrical events that occurs with every heartbeat.
10+ Cardiac Cycle Phases Diagram. The phase of relaxation diastole and the phase of contraction systole are included in this cycle. As the ventricles relax from the previous cycle, blood passively flows into the ventricles from the atria through the open atrioventricular (av) valves. Ventricular diastole is followed by systole, systole, where the ventricles contract and. Preload denotes the initial stretching of cardiomyocytes prior to contraction, so the 'load' is the stretch of the cardiac muscle at the end of diastole.
