Question
Chapter 20.4, Problem 14BYGO
Summary Introduction
To write:
About the cardiac cycle, systole and diastole along withthe effect of shortening the diastole on the heart rate and the duration of thecardiac cycle.
Introduction:
The terms cardiac cycle, systole, and diastole areassociated with the heart rate. Heart rate is defined as the number of times aheart beats in a minute. The rate of heartbeat varies depending on the need of anindividual's body.
