the function of the pericardial fluid is to quizlet
Pericardial fluid The pericardial fluid reduces friction within the pericardium by lubricating the epicardial surface allowing the membranes to glide over each other with each heart beat.[2]
Pericardium The pericardium is a double-walled sac containing the heart and the roots of the great vessels. The pericardial sac has two layers, a serous layer and a fibrous layer. It encloses the pericardial cavity which contains pericardial fluid.
Pericardium The pericardium fixes the heart to the mediastinum, gives protection against infection, and provides the lubrication for the heart. It receives its name from Ancient Greek peri (περί; "around") and cardion (κάρδιον; "heart").
Pericardium 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.
