Answer: Fibrous pericardium and Serous Pericardium
Explanation:
The pericardium can be defined as the fibroserous sac( double layered) which covers the whole heart. The gap between two layers of serous pericardium is filled with serous fluid. This fluid protects the heart from external shocks.
Fibrous pericardium
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.
