Question
Chapter 20, Problem 13RAC
Summary Introduction
Introduction:
During a single cardiac cycle, all chambers within the heart experience alternate periods of contraction and relaxation. A cardiac cycle includes all the events within the heart from the start of one heartbeat to the initiation of the next.
