Pericardium is an intense, two-layer membranous sac that encases the HEART. The pericardium's stringy external layer, called the sinewy pericardium, shields the heart from contact with the chest divider and different structures in the chest, including the LUNGS and the sternum. The pericardium wraps totally around the heart, stretching out around the bases of the immense vessels (AORTA, predominant and sub-par VENA CAVA, pneumonic ARTERY, aspiratory VEIN) as they emerge from the heart. Two tendons join the highest point of the pericardium to the back of the sternum. Different tendons freely interface the base of the pericardium to the DIAPHRAGM. These structures grapple the heart in its place in the chest.

The internal layer of the pericardium is a dingy envelope. Its two surfaces are the parietal pericardium, which contacts the sinewy pericardium, and the epicardium, which covers the MYOCARDIUM to some degree like a wet tissue. Inside the envelope is a watery liquid that greases up the heart. The inward pericardium frames an about frictionless control field for the pulsating heart. The pericardium is helpless against INFLAMMATION and INFECTION (PERICARDITIS).

For encourage talk of the pericardium inside the setting of cardiovascular structure and capacity, please observe the outline area "The Cardiovascular System."
