The cardiac cycle consists of two main phases: systole and diastole. During systole, the atria and ventricles contract, resulting in an increase in pressure within the ventricles and an ejection of blood from the ventricles into the arteries. The electrical activity within the myocardium during this phase is ...

Did you know?
The two main phases of the cardiac cycle are systole and diastole, and they follow each other in sequence. Each stage in the cardiac cycle contains important stepswhich direct the flow of blood properly. These steps include contractions of heart chambers and the proper opening and closing of specific … Visa mer The cardiac cycle varies in different organisms, due to changes in the structure of the heart.

WebbThe cardiac cycle is a continuous sequence of events that occur in the heart, including both contraction (systole) and relaxation (diastole) of the atria and ventricles. The cycle can be divided into several phases as described below: During this phase, both atria and ventricles are in a relaxed state (diastole). diagonal iowa countyWebbExplain the pressure and volume changes in the ventricle during the following phases of the cardiac cycle; a.
