Pericardium - definition and function What is Pericardium, definition and function. Pericardium is a tough, two-layer membranous sac that encloses the HEART. The pericardium’s fibrous outer layer, called the fibrous pericardium, protects the heart from contact with the chest wall and other structures in the chest, including the LUNGS and the sternum.he inner layer of the pericardium is a filmy envelope. Its two surfaces are the parietal pericardium, which contacts the fibrous pericardium, and the epicardium, which covers the MYOCARDIUM somewhat like a wet tissue. Inside the envelope is a watery fluid that lubricates the heart.

Pericardium The serous pericardium, in turn, is divided into two layers, the parietal pericardium, which is fused to and inseparable from the fibrous pericardium, and the visceral pericardium, which is part of the epicardium.he pericardium is a tough double layered fibroserous sac which covers the heart. The space between the two layers of serous pericardium (see below), the pericardial cavity, is filled with serous fluid which protects the heart from any kind of external jerk or shock.

Definitions &Translations a fibroserous sac that surrounds the heart and the roots of the great vessels. It consists of the serous pericardium and the fibrous pericardium. The serous pericardium consists of the parietal layer, which lines the inside of the fibrous pericardium, and the visceral layer, which adheres to the surface of the heart.

Pericardial Window The pericardium is a thin, fluid-filled sac that envelopes the heart. Pericardial effusion is a disease characterised by an excess accumulation of fluid in the sac, leading to impairment in the heart’s functions.

Pericardium The pericardium is a tough double layered fibroserous sac which covers the heart. The space between the two layers of serous pericardium (see below), the pericardial cavity, is filled with serous fluid which protects the heart from any kind of external jerk or shock.There are two layers to the pericardial sac: the outermost fibrous pericardium and the inner serous pericardium.n between the parietal and visceral pericardial layers there is a potential space called the pericardial cavity, which contains a supply of lubricating serous fluid known as the pericardial fluid. When the visceral layer comes into contact with heart (not the great vessels) it is known as the epicardium.

Bacterial Pericarditis The pericardium is a thin membrane that surrounds and protects your heart. This membrane helps prevent infection and also keeps your heart from expanding too much. Diseases and health problems can cause an inflammation of this membrane, or pericarditis. The causes of pericarditis include:

Pericardial Disorders 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. It can be from a virus or other infection, a heart attack, heart surgery, other medical conditions, injuries, and certain medicines. Pericardial effusion - the buildup of fluid in the sac Cardiac tamponade - a serious problem in which buildup of fluid in the sac causes problems with the function of the heart

Overview Pericardial effusion (per-e-KAHR-dee-ul uh-FU-zhun) is the accumulation of too much fluid in the double-layered, sac-like structure around the heart (pericardium). The space between the layers normally contains a thin layer of fluid.

pericardium The serous membrane (covering membrane) which, in humans and other vertebrates, forms the wall of the pericardial cavity and holds the heart in place. The pericardium is made of two thin layers of tissue. Immediately surrounding the heart, and attached to it, is the visceral pericardium, or epicardium.

- Pericardium: The conical sac of fibrous tissue that surrounds the heart and the roots of the great blood vessels.The pericardium's outer coat (the parietal pericardium) is tough and thickened, loosely cloaks the heart, and is attached to the central part of the diaphragm and the back of the breastbone.ts inner coat (the visceral pericardium or epicardium) is double, with one layer closely adherent to the heart and the other lining the inner surface of the outer coat. The intervening space between these layers is filled with pericardial fluid.

Anatomy of the Heart: Pericardium The pericardium is divided into three membrane layers: 1  Fibrous Pericardium - the outer fibrous sac that covers the heart. It provides an outer protective layer that is attached to the sternum by sternopericardial ligaments. 2  Parietal Pericardium - layer between the fibrous pericardium and visceral pericardium.

Pericardium The pericardium (from the Greek περί, around and κάρδιον, heart) is a double-walled sac containing the heart and the roots of the great vessels. The pericardial sac has two layers, a serous layer and a fibrous layer. It encloses the pericardial cavity which contains pericardial fluid.The pericardium fixes the heart to the mediastinum, gives protection against infection, and provides the lubrication for the heart.he serous pericardium, in turn, is divided into two layers, the parietal pericardium, which is fused to and inseparable from the fibrous pericardium, and the visceral pericardium, which is part of the epicardium.
