Which layer of the pericardium is responsible for reducing friction during heartbeats?

What is the maximum volume of pericardial fluid expected in the pericardial cavity?

What condition is characterized by inflammation of the pericardium and may cause a friction rub?

How does the pericardium assist in the heart's function during movement?

Pericardium Function

The pericardium is a double-walled sac surrounding the heart.
It allows the heart to beat smoothly and expands with each heartbeat.
It prevents overexpansion of the heart.

Pericardium Structure

The Fibrous Pericardium is the tough outer layer.
The Serous Pericardium is the inner layer with two parts:
- Parietal Layer lines the fibrous pericardium.
- Visceral Layer is the epicardium and is part of the heart.
The Pericardial Cavity is the space between the parietal and visceral layers.
- It contains 5 to 30 mL of fluid to reduce friction.
- Inflammation of the pericardium is known as Pericarditis.
  - Pericarditis can cause a friction rub, which sounds like a grating sensation.

Pericardium Structure

The pericardium is a two-layered membrane that encloses the heart, composed of the fibrous pericardium and the serous pericardium.
The fibrous pericardium is the tough outer layer.
The serous pericardium has two layers: the parietal layer, which lines the fibrous pericardium, and the visceral layer (epicardium), which is adhered to the heart's surface and is the outermost layer of the heart itself.
The space between the parietal and visceral layers of the serous pericardium is called the pericardial cavity and is filled with pericardial fluid.
The pericardial fluid provides lubrication, reducing friction during heart contractions.
Inflammation of the pericardium is called pericarditis. Pericarditis can produce a friction rub, an audible sound caused by the inflamed pericardium rubbing against the heart.
