The elastic nature of the pericardium allows it to accommodate a small amount of extra fluid, roughly 80 to 120 mL, in the acute setting. [2] However, once a critical volume is reached, even small amounts of extra fluid can rapidly increase pressure within the pericardium.
Serous membrane fluid collects on microvilli on the outer layer and acts as a lubricant and reduces friction from muscle movement. This can be seen in the lungs, with the pleural cavity. Pericardial fluid is a serous fluid secreted by the serous layer of the pericardium into the pericardial cavity. The pericardium consists of two layers, an ...
The total body of water is divided into fluid compartments, [1] between the intracellular fluid compartment (also called space, or volume) and the extracellular fluid (ECF) compartment (space, volume) in a two-to-one ratio: 28 (28–32) liters are inside cells and 14 (14–15) liters are outside cells.
The two layers of the serous membrane enclose the pericardial cavity (the potential space) between them. [1] This pericardial space contains a small amount of pericardial fluid, normally 15-50 mL in volume. [2]
A small amount of fluid, called transcellular fluid, does exist normally in such spaces. For example, the aqueous humor, the vitreous humor, the cerebrospinal fluid, the serous fluid produced by the serous membranes, and the synovial fluid produced by the synovial membranes are all transcellular fluids. They are all very important, yet there is ...
Extracellular fluid provides the medium for the exchange of substances between the ECF and the cells, and this can take place through dissolving, mixing and transporting in the fluid medium. [13] Substances in the ECF include dissolved gases, nutrients, and electrolytes, all needed to maintain life. [14]
Visceral fat is the type of fat that surrounds your internal organs in your abdomen. It can be particularly worrisome because it's housed in places where fat shouldn’t be stored in excess. While ...
The pericardium consists of two layers, an outer fibrous layer and the inner serous layer. This serous layer has two membranes which enclose the pericardial cavity into which is secreted the pericardial fluid. The fluid is similar to the cerebrospinal fluid of the brain which also serves to cushion and allow some movement of the organ. [1]
