GROSS ANATOMY

Detailed explanation-1: -The pericardium is made up of an outer layer of connective tissue that holds the heart in place within the chest, protects it from inflammation, and acts as a barrier against infection. It also keeps the heart from stretching out and filling up with too much blood.

Detailed explanation-2: -The pericardium is a fibrous sac that encloses the heart and great vessels. It keeps the heart in a stable location in the mediastinum, facilitates its movements, and separates it from the lungs and other mediastinal structures. It also supports physiological cardiac function.[1][2][3]

Detailed explanation-3: -Anatomy. The pericardium is a dual-layered structure enveloping the heart and proximal great vessels. It consists of an inner visceral pericardium (also called the epicardium when in contact with the myocardium), and an outer parietal pericardium, composed of layers of collagen fibrils and elastin fibers.

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: -This is the thin sac (membrane) that surrounds the heart. The pericardium holds the heart in place and helps it work right. There is a small amount of fluid between the inner and outer layers of the pericardium.
