The pericardium's outer coat is called the parietal pericardium which is tough and thickened, loosely cloaks the heart, and is attached to the central part of the diaphragm and the back of the breastbone

Its inner coat is called the visceral pericardium or epicardium which is double, with one layer closely adherent to the heart and the other lining the inner surface of the outer coat

The intervening space between these layers is filled with pericardial fluid

This small amount of fluid acts as a lubricant to allow normal heart movement within the chest
