To analyze systole and diastole in more detail the cardiac cycle is usually divided into seven phases.
Cardiac cycle steps. Action potential physiology phases and steps made easy. Filling phase the ventricles fill during diastole and atrial systole. During a cardiac cycle each ventricle pumps out approximately 70 mL of blood which is called the stroke volume.
The pressure in the right atrium increases as blood flows into it. 1 Isovolumic relaxation 2 Inflow 3 Isovolumic contraction 4 Ejection. A cardiac cycle is defined as the steps involving the conversion of deoxygenated blood to oxygenated blood in the lungs and pumping it by the heart to the body through the aorta 40.
These steps include contractions of heart chambers and the proper opening and closing of specific heart valves. See Wiggers diagram which presents the stages label-wise in 3412 order left-to-right. Each stage in the cardiac cycle contains important steps which direct the flow of blood properly.
The cardiac cycle has 2 phases systole and diastole defined by depolarization and contraction vs repolarization and relaxation. The diastole phase and the systole phase. The events of the cardiac cycle start with a spontaneous action potential in the sinus node as we described previously.
OF PHYSIOLOGY CARDIAC CYCLE 2. Duration of a cardiac cycle is 08 seconds. Blood flows into the left atrium from the four pulmonary veins.
In the diastole phase heart ventricles relax and the heart fills with blood. Atrial and Ventricular diastole chambers are relaxed and filling with blood Atrial systole atria contract and remaining blood is pushed into ventricles. Both atria contract atria systole to forcibly fill the ventricles with blood.
