Explanation:

The pericardial sac has two layers, a serous layer and a fibrous layer. It encloses the pericardial cavity which contains pericardial fluid. The pericardium fixes the heart to the mediastinum, gives protection against infection and provides the lubrication for the heart.

Second, through its membranous function, the pericardium shields the heart by reducing external friction and acting as a barrier against extension of infection and malignancy. Third, through its ligamentous function, the pericardium anatomically fixes the heart.
