It lines the inside of the heart chambers and covers the heart valves. The endocardium is made of endothelial cells and provides a smooth surface to minimize friction as blood flows through the heart. It also plays a role in regulating myocardial function and protecting the heart from abnormal clotting.<\/li>\n\n\n\n<li><strong>Myocardium<\/strong> \u2013 This is the <strong>middle layer<\/strong> and is made up of cardiac muscle tissue. It is the thickest layer and is responsible for the contractile function of the heart, pumping blood throughout the body. The myocardium\u2019s thickness varies depending on the chamber: the left ventricle has the thickest myocardium because it pumps blood to the entire body.<\/li>\n\n\n\n<li><strong>Epicardium<\/strong> \u2013 This is the <strong>outermost layer<\/strong> of the heart wall. It is also called the visceral layer of the serous pericardium. The epicardium serves as a protective layer and contains blood vessels, nerves, and fat.
