The parietal pericardium serve to protect the heart from damage and it reduce friction, and is made of the serous membrane.
It is made from thick connective tissue and it is attached to diaphragm. It holds the heart in place in the chest cavity and protects from infections.
Functions of parietal pericardium
Parietal pericardium protects the heart from various type of infections. Parietal pericardium is the layer situated between the fibrous pericardium and visceral pericardium.
Pericardium is the fibrous tissue that surrounds the heart and the roots of the great blood vessels
The pericardium's outer coat is called the parietal pericardium which is tough and thickened, loosely cloaks the heart, and is attached to the central part of the diaphragm and the back of the breastbone
Its inner coat is called the visceral pericardium or epicardium which is double, with one layer closely adherent to the heart and the other lining the inner surface of the outer coat
The intervening space between these layers is filled with pericardial fluid
This small amount of fluid acts as a lubricant to allow normal heart movement within the chest
the difference between rocks and minerals .A mineral is a naturally not occurring, inorganic solid with a definite chemical composition and a crystalline structure formed by geological processes. A rock is an aggregate of one or more minerals whereas a rock may also include organic remains and mineraloids.
