Study Notes
- Total body fluid is 55-60% of body weight in young men and 45-50% in young women.

- 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.
