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. Both of these layers function in lubricating the heart to prevent friction during heart activity.he 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.
Parietal layer of serous pericardium: It lines the fibrous pericardium and is reflected around the roots of great blood vessels. At the region of reflection, it becomes continuous with the visceral layer of serous pericardium, which covers the heart closely.Visceral layer of serous pericardium: This layer is closely applied to the heart and is often called the epicardium.There exists a slit like space between the parietal and visceral layers of serous pericardium. This space is known as pericardial cavity and it contains a small amount of tissue fluid called pericardial fluid.ericardium is a fibroserous sac, which encloses the heart and roots of great vessels. It has two primary functions. Firstly, it restricts excessive movements of the heart so that injury to this vital organ of human body is avoided.
