The myocardium is the middle layer and finally the endocardium is the innermost. The heart is composed of different cell types which all contribute to structural‚ biochemical‚ mechanical‚ and electrical properties. Forming the walls of the heart are atrial and ventricular cardiomyocytes. Cells specialize in different roles. They determine the function of a tissue in the human body. Endothelial cells form the endocardium which is the interior lining of blood vessels and cardiac valves. Over 50 percent
