Explanation The various activities of the heart are performed by the different chambers present in it. These four chambers include left ventricle, right atrium, left atrium, and right ventricle. The heart has three surfaces - anterior surface, posterior surface, and inferior surface. The posterior base of the heart is formed by the left atrium, and the right atrium forms the right border...

Question

Chapter 19, Problem 18RQ

Summary Introduction

To review:

The heart chamber which appears the largest upon visuailzation of the anterior surface of the heart.

Introduction:

The body tissues require continuous supply of oxygen for their efficient functioning. The heart is the muscular pumping organ that takes the deoxygenated blood from the body and pumps this blood for oxygenation into the lungs. This oxygenated blood is then received by the heart, which is further pumped all around the body tissue.
