What Is the Cardiac Cycle?
The cardiac cycle is a series of events that take place continuously in the heart to ensure blood is effectively pumped and circulated throughout the body It is the term used to describe the sequence of mechanical and electrical processes that lead to the heartbeat. The cycle begins with the atrial contraction, followed by the ventricular contraction, and ends with the relaxation of the heart's chambers and then the isovolumic process of filling.
The cycle is defined by several specific components. The first segment is the atrial systole, during which the atria contract and squeeze blood into the ventricles. This is followed by the ventricular systole, in which the ventricles contract and eject blood into the aorta and pulmonary arteries. Then, the isovolumic relaxation period occurs, during which pressure is equalized and the heart refills with blood. Lastly, the ventricular diastole occurs, during which the atria and ventricles relax and fill with blood.
The cardiac cycle and the various parts of it are essential for our bodies to function. They ensure that oxygen and nutrients are delivered to our cells, and that waste materials are removed from them. In addition, the release of hormones and other substances necessary for our health are regulated during the cycle.
