Compartment (pharmacokinetics)
From Infogalactic: the planetary knowledge core
In pharmacokinetics, a compartment is a defined volume of body fluids. It is distinguished from anatomic compartments, which are bounded by fasciae. It is used in multi-compartment models.
Examples
There are five major body compartments:[1]
The transcellular compartment includes fluids in the pleural cavity or peritoneal cavity.
Comparison table
| Compartment | estimated % of body mass[1] |
|---|---|
| blood plasma | 5 |
| interstitial fluid | 16 |
| fat tissue | 20 (see also body fat percentage) |
| intracellular fluid | 35 |
| transcellular fluid | 2 |
