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.
In 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.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.
