Study Notes
Body Water Composition
- Water makes up 60% of a man's body weight and 50% of a woman's body weight.
Body Water Distribution
- Body water is divided into two major compartments: intracellular fluid (ICF) and extracellular fluid (ECF).
Intracellular Fluid (ICF) Compartment
- Contains 55% to 65% of total body water.
Extracellular Fluid (ECF) Compartment
- Contains 35% to 45% of total body water.
- Further divided into two sub-compartments: interstitial space and intravascular space.
Interstitial Space
- Comprises approximately three-fourths of ECF.
Intravascular Space
- Contains one-fourth of ECF.
