The pericardial sac.
The pericardial cavity
Fibrous pericardium and serous pericardium. The serous pericardium is made up of an outer parietal layer that is fused to the fibrous pericardium and an inner visceral layer (aka epicardium) that is a layer of the heart wall and adheres tightly to the heart.
The space between the parietal and visceral layers of the pericardium is called the pericardial cavity and it is filled with a thin layer of fluid called pericardial fluid. The pericardial fluid lubricates the two membranes, allowing them to glide over each other without any friction when the heart beats.
between the parietal and visceral pleurae
The peritoneal cavity is the space between the visceral and parietal peritoneum in the abdominal cavity.
The difference between these two pleura is that the parietal pleura is the outtermost covering of the lung which is adhered to the inner thoracic wall, while the visceral pleura is the lining which is directly adhered to the lung itself. The space between these two pleuras is know as the pleual cavity.

The pericardial space lies between the pericardium and the epicardium.
Yes, the visceral pericardium adheres to the outside surface of the myocardium (heart muscle), while the parietal pericardium lies outside of the visceral pericardium. There is a small amount of lubricating fluid between these two membranes in the potential space known as the pericardial space. If an abnormal amount of fluid of any kind builds up in this space, it is called a pericardial effusion.
The pericardial space is located in between the parietal and visceral pericardium, contains 10-20 ml of fluid to cushion and protect the heart.

But, the pericardium is actually TRIPLE layered: the visceral layer, the parietal layer, and the fibrous layer (fibrosa).The visceral pericardium is the inner-most layer of the pericardium, and is also known as the Epicardium as it "lays" upon the heart.The Pericardial Cavity lies between the visceral pericardium and the parietal pericardium. This cavity is filled with pericardial fluid which serves as a shock absorber by reducing friction between the visceral and parietal layers. The parietal pericardium is an outer layering wall of the Pericardial Cavity between the pericardial membranes.The outer-most layer is the fibrous layer (fibrosa), and contains nerves, blood vessels, and lymphatics. This is the layer that can become inflamed, called pericarditis. (As opposed to, endocarditis, which is inflammation of the insidelayer of the heart.)
No, the pericardium is the membrane covering the heart. There is a tough fibrous pericardium and a thin membranous portion called the epicardium. There is a potential space created by these overlying membranes called the pericardial space. The chambers of the heart are the left and right atrium and the left and right ventricles.outside the hear
The double-layered membrane surrounding the heart is called the pericardium. The pericardium is a thick, membranous sac that secretes a lubricating liquid. There is a thin inner layer that sits directly on and is attached to the surface of the heart, called the epicardium. There is a very small space, which usually has a very small amount of fluid, called the pericardial space, and a tough outer layer called the pericardium (peri = around and cardium = heart).
A double membranous sac which envelops and protects the heart. The layer in contact with the heart is referred to as the visceral layer, the outer layer in contact with surrounding organs is the parietal pericardium. In between the two layers is the pericardial space. A double-layered serous membrane that surrounds the heart.
between the parietal and visceral pleurae
Surrounding the heart is a fibrous sac called the pericardium. This sac protects the heart, and is actually composed of two layers: an inner visceral one and an outer parietal one. When the heart moves (i.e. when the heart beats), these two layers move with it. For this to happen, it is important that there is no friction between the two layers of the pericardium, which is why pericardial fluid lines the inner space between the them. Much like oil in an engine, the pericardial fluid makes for less friction between the inner and outer layer of the pericardium.
