Detailed explanation-1: -The pericardium is the fibrous sac that surrounds the heart. It can be divided into three layers, the fibrous pericardium, the parietal pericardium, and the visceral pericardium. The parietal and visceral pericardia together form the serous pericardium.

Detailed explanation-2: -Your pericardium is a fluid-filled sac that surrounds your heart and the roots of the major blood vessels that extend from your heart. Conditions that affect your pericardium include pericarditis, pericardial effusion and constrictive pericarditis.

Detailed explanation-3: -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-4: -The pericardium, also called pericardial sac, is a double-walled sac containing the heart and the roots of the great vessels. It has two layers, an outer layer made of strong connective tissue (fibrous pericardium), and an inner layer made of serous membrane (serous pericardium).

Detailed explanation-5: -The pericardium acts as mechanical protection for the heart and big vessels, and a lubrication to reduce friction between the heart and the surrounding structures. A very important role in all aspects of pericardial functions is played by mesothelial cells.
