How many layers does the pericardium consist of?

Explanation:
The pericardium has three layers: the outer fibrous pericardium and the serous pericardium, which is double-layered with a parietal layer lining the fibrous pericardium and a visceral layer (epicardium) covering the heart. The space between the parietal and visceral serous layers is the pericardial cavity containing lubricating fluid. Counting fibrous, parietal serous, and visceral serous gives three layers in total.
