This volume presents a basic overview of the human heart. The heart is a myogenic muscular organ found in all animals with a circulatory system (including all vertebrates), that is responsible for pumping blood throughout the blood vessels by repeated, rhythmic contractions. This work contains a quick look at mankind's knowledge about the human heart throughout history. It also looks at human heart anatomy, its pumping mechanism, disease and threats to cardiopulmonary health, medical treatment for heart disease, and appendixes that provide awareness of heart attacks, diet and proper exercise.
