This layer is the most superficial layer which consists of dense connective tissue. This layer of the heart protects it from over filling of blood, anchors the heart to the surrounding wall.
Serous pericardium
This layer provides lubrication to the heart by resisting the friction which occurs during the various type of heart function.
