Define a cardiac cycle and the cardiac output.

(N/A) cardiac cycle is defined as the sequential events in the heart that occur from the beginning of one heartbeat to the beginning of the next. It consists of three main stages: atrial systole, ventricular systole, and joint diastole.
Cardiac output is defined as the volume of blood pumped out by each ventricle per minute. It is calculated by the product of stroke volume and heart rate ($Cardiac Output = Stroke Volume \times Heart Rate$).
