Study Notes
- Total body fluid is 55-60% of body weight in young men and 45-50% in young women.
- Body fluid is distributed between intracellular and extracellular fluid.
- Intracellular fluid is 2/3 of body fluid and 40% of total body weight.
- Extracellular fluid is 1/3 of body fluid and 20% of total body weight.
- Extracellular fluid can be divided into interstitial fluid, blood plasma, and transcellular fluid volume.
- Interstitial fluid surrounds all cells except blood cells and includes lymph.
- Blood plasma is the fluid portion of the blood.
- Transcellular fluid volume represents fluid in structures lined by epithelium.
- Examples of transcellular fluid volume include digestive secretion, sweat, and cerebrospinal fluid.
- Edema is the palpable swelling produced by expansion of interstitial fluid volume.
