Explanation The flow of blood into the aorta is controlled by ventricular contraction pattern. Further, this contraction is controlled by the conducting system of the heart which contains conducting fibers and cardiac muscle cells. These fibers initiate electrical impulse which helps in the contraction of heart chambers. Ventricular contraction initiates at the heart apex to eject blood superiorly into the arteries...

Question

Chapter 19, Problem 9CRCAQ

Summary Introduction

To review:

The features of the heart that contribute to the sequence of ventricular contraction and flow of blood from the apex of the heart into the arteries.

Introduction:

The heart has four chambers known as left atrium or ventricle and the right atrium or ventricle. The contraction of the chamber occurs when the blood flows from one chamber to the other chamber of the heart. The contraction of atrium occurs when the blood moves from the atrium to the ventricle while ventricular contraction takes place during the blood flow through the ventricle to the arteries.
