Question

Please help explain cardiac cycle in simple words. ....please....

Answer 1

The cardiac cycle refers to a complete heartbeat from its generation to the beginning of the next beat, and so includes the diastole, the systole, and the intervening pause. The frequency of the cardiac cycle is described by the heart rate, which is typically expressed as beats per minute. Each beat of the heart involves five major stages

Answer 2

There are two phases of a heartbeat. Diastole is the term used to describe the relaxation of the heart. When the heart is in this state of relaxation, the pressure within the heart is very low and blood is passively flowing through the atria and into the ventricles through the open atrioventricular valve, or AV valve.
