Detailed explanation-1: -The pericardium consists of two layers: the fibrous and the serous. The fibrous pericardium is a conical-shaped sac. Its apex is fused with the roots of the great vessels at the base of the heart. Its broad base overlies the central fibrous area of the diaphragm with which it is fused.
Detailed explanation-2: -The pericardium, also called pericardial sac, is a double-walled sac containing the heart and the roots of the great vessels.
Detailed explanation-3: -There are two layers of serous membranes (parietal and visceral) with the outer layer being the parietal pericardium which attaches the heart to the mediastinum and has fibrous tissue so the heart does not over-expand. The inner visceral layer is also called the epicardium and it lines the surface of the heart.
