Answer:
The cardiac wall contains three layers: epicardium, myocardium and endocardium.
Step-by-step explanation:
The epicardium, the outermost layer of the heart, also has a large amount of adipose tissue. It is the same as the visceral layer of the serous pericardium.
The myocardium, located below the epicardium, is the cardiac muscle tissue as such, responsible for pumping the blood through the circulatory system through contraction.
The endocardium is the membrane that covers the inside of the heart. This membrane surrounds the inside of blood vessels, transporting blood through a continuous tunnel of endothelial cells throughout the cardiovascular system.
