Body fluid
This article about biology may be excessively human-centric. |
Body fluids, bodily fluids, or biofluids, sometimes body liquids, are liquids within the body of an organism.[1] In lean healthy adult men, the total body water is about 60% (60–67%) of the total body weight; it is usually slightly lower in women (52–55%).[2][3] The exact percentage of fluid relative to body weight is inversely proportional to the percentage of body fat. A lean 70 kg (150 lb) man, for example, has about 42 (42–47) liters of water in his body.
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 ECF compartment is divided into the
The interstitial fluid compartment is divided into the
The vascular volume is divided into the
Compartments by location
- intracellular fluid (ICF), which consist of cytosol and fluids in the cell nucleus[6]
- Extracellular fluid
- Intravascular fluid (blood plasma)
- Interstitial fluid
- Lymphatic fluid (sometimes included in interstitial fluid)
- Transcellular fluid
Health
Body fluid is the term most often used in medical and health contexts. Modern
Clinical samples
Clinical samples are generally defined as non-infectious human or animal materials including
Sampling
Methods of sampling of body fluids include:[citation needed]
- Blood sampling for any blood test, in turn including:
- Arterial blood sampling, such as radial artery puncture
- Venous blood sampling, also called venipuncture
- Lumbar puncture to sample cerebrospinal fluid
- Paracentesis to sample peritoneal fluid
- pleural fluid
- Amniocentesis to sample amniotic fluid
