Top 30 Doctor insights on: Average Life Expectancy After Heart Transplant Transplant (Definition) 1  In medicine: a transfer from one body or body part to another of an organ (liver, heart, lung, kidney, pancreas bowel) or tissue (hand, face, hair). The immune system fights foreign invaders (like infections) so it will reject transplants from other people (allotransplants) because they look like infections.

Library of Notes This is the thickest of all the layers of the heart. The pericardium is the double walled sac that contains the heart and the roots of the great vessels that leave from or enter the heart. Fibrous Pericardium: The fibrous pericardium is a strong layer which covers the heart. It is made up mostly of connective tissue. Its job is to protect the heart from overstretching and also anchor it in place. This layer is the most superficial layer of the pericardium.

- The pericardium lies within the mediastinum, the portion of the thoracic cavity between the left and right pleural cavities (Figure 1-11d). The connective tissue of the mediastinum surrounds the pericardial cavity and heart, the large arteries and veins attached to the heart, and the thymus, trachea, and esophagus.he relationship between the heart and the cavity resembles that of a fist pushing into a balloon (Figure 1-11b). The wrist corresponds to the base (attached portion) of the heart, and the balloon corresponds to the serous membrane that lines the pericardial cavity. The serous membrane is called the pericardium.

The Pericardium The Pericardium. 1  The pericardium (G. around the heart) is a double-walled fibroserous sac that encloses the heart (G. kardia) and the roots of the great vessels. 2  It is located in the middle mediastinum, posterior to the body of the sternum and the 2nd to 6th costal cartilages, and anterior to T5 to T8 vertebrae. The pericardium consists of two parts : (1) a strong external layer composed of tough fibrous tissue, called the fibrous pericardium, and (2) an internal double-layered sac composed of a transparent membrane called the serous pericardium.

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.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. Both of these layers function in lubricating the heart to prevent friction during heart activity.

Mediastinum or Pericardial? Rating Newest Oldest. Best Answer: Odd name not to be able to locate the heart. The heart is located in the thoracic cavity, in the portion of the chest known as the mediastenum- the region between the pleural sacs and containing all the thoracic viscera except the lungs. The pericardium is the thin sac or membrane which contains the heart and the roots of the great blood vessels. When you refer to a body cavity, you would say the heart lies in the thorax or thoracic cavity. Within that cavity, it lies within the mediastenum, and is surrounded by the pericardium.

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.

What are the three layers of heart tissue? The pericardium is a protective sac surrounding the heart, which consists of two parts: the inner serous pericardium and the outer fibrous pericardium. The serous pericardium has two layers--the visceral and the parietal. The visceral pericardium, also called the epicardium, is the inner layer, in contact with the heart muscle itself. The parietal pericardium is the outer, fibrous layer.

What is the medical term meaning the sac that contains the heart? Peri - means around, and - cardium means heart. The pericardium is a double walled sac that encloses the heart, and the proximal ends of the aorta, vena cava, and the pulmonary artery. The visceral layer is next to the heart, then a bit of fluid, and the parietal layer is outermost. In trauma, it can become filled with blood and impinge on the heart.

Is Fluid Around the Heart Dangerous? One layer of the pericardial tissue is fibrous, connecting the heart to surrounding tissues; the other layer is serous, meaning it normally contains a small amount of pale yellow fluid that prevents friction as the heart pumps.
