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 is a membrane, or sac, that surrounds your heart. It holds the heart in place and helps it work properly. Problems with the pericardium include: Pericarditis-an inflammation of the sac.

Detailed explanation-3: -A human heart is enclosed in a double-walled sac called pericardium.

Detailed explanation-4: -The pericardium is the membrane that encloses the heart and the roots of the major heart vessels, consisting of an outer fibrous layer (fibrous pericardium) and an inner double serous membrane layer (serous pericardium).

Detailed explanation-5: -A fibrous sac called the pericardium surrounds the heart. This sac has two thin layers with fluid between them. This fluid reduces friction as the two layers rub against each other when the heart beats.
