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.

The outer layer of the pericardium surrounds the roots of your heart's major blood vessels.Ligaments attach this layer to your spinal column, diaphragm, and other parts of your body. The inner layer of the pericardium is attached to the heart muscle.ericarditis is inflammation of the pericardium, causing the amount of fluid between the two layers of the pericardium to increase. This increased fluid presses on the heart and restricts its pumping action.
