Detailed explanation-1: -A fibrous sac called the pericardium surrounds the heart and major blood arteries. It helps the heart’s motions, maintains it stable in the mediastinum, and keeps it safe away from the lungs and other mediastinal structures.

Detailed explanation-2: -Pericardium: The heart is covered by a double membranous protective layer known as the pericardium. The space that is present between the two pericardial membranes is filled with a fluid called pericardial fluid. It prevents the heart from mechanical injury and shocks and also helps to reduce friction.

Detailed explanation-3: -The pericardium is the name given to the membranes which cover the heart. It is a double layer forming a closed sac. The layer which covers the heart is called the epicardium and consists of a glistening smooth surface of epithelium attached to the heart by connective tissue.

Detailed explanation-4: -What is the pericardium? Your pericardium is a protective, fluid-filled sac that surrounds your heart and helps it function properly. Your pericardium also covers the roots of your major blood vessels as they extend from your heart.

Detailed explanation-5: -Pericardium is a double layered protective covering of the heart. Outer layer is the parietal pericardium and the inner layer is visceral pericardium enclosing a pericardial cavity filled with pericardial fluid.
