Summary Introduction
Introduction:
Heart is a vital muscular organ that pumps blood through the blood vessels in the body. In vertebrates, it is divided into four chambers: two ventricles (left and right) and two atria (left and right).
The walls comprise three layers: the myocardium, the outer epicardium, and the innermost endocardium.
