Question
Chapter 20, Problem 20.4.1AYLO
Summary Introduction
To analyze:
The name and the location of the pacemaker of the heart.
Introduction:
The cardiac conduction system controls the route and timing of stimulation of the four heart chambers to ensure that they are coordinated with each other. The cardiac conduction system is constituted by cardiocytes which are specialized to generate and conduct electrical signals.
