Cardiac muscle makes up the wall of the heart. It contracts to pump blood around the body. Smooth muscle is found in the walls of all hollow organs except the heart.
There are layers to the wall are myocardium, epicardium and andocardium. The heart is covered by a protective sack called the pericardium.
