Explanation The heart rate is about 70-time beats per minute. A single heartbeat takes about 0.8 sec to complete which is called “cardiac cycle” . During the cardiac conduction, the following events take place: Step I: In this step, there is a generation of “cardiac impulse”. The conduction of impulse is generated from the presence of the sinoatrial (SA) node which is present in the right wall of the atrium. The contraction of SA node results in the conduction of nerve impulses that transmit throughout the wall of the heart. This event causes the event of atrium contraction. Step II: The impulse travels from the SA node to the atrioventricular (AV) node. The AV node is present at the base septum of the right atrium. During the impulse conduction from SA node to the AV node, there would be a gap of about a “tenth of a second.” The time gap provides the time for atrial contraction and transfers its contents into the ventricles before the contraction of ventricles...

Question

Chapter 44.5, Problem 1C

Summary Introduction

To list: The sequence of events that occur during cardiac conduction.

Introduction: Heart is the main organ of a circulatory system. It pumps the blood and fulfills the requirement of various body systems. Oxygenation of various systems is one of the major functions of the circulatory system. The circulatory system consists of arteries, veins, capillaries, and a heart. The heart is responsible for the removal of metabolic wastes from the organism’s body.
