Answer:
It is a cycle of contraction and relaxation of atria and ventricles.
Explanation:
The cardiac cycle is the sequence of electrical, mechanical, sound and pressure events, related to the flow of blood through the cardiac cavities, the contraction and relaxation of each of them (atria and ventricles), the closure and opening of Valves and noise production. This process takes place in less than a second. The reciprocal of the duration of a cycle is the heart rate (as usually expressed in beats per minute, multiply by 60 if the duration is measured in minutes).
