Answer
Fluid compartments are areas separated by selectively permeable membranes and differing from each other in chemical composition.
65% of fluid is in the ICF and 35% is in the ECF.
A typical young adult male is 55% - 60% water.
Work Step by Step
Fluid compartments are just areas where water occurs in the body.
The ICF contains about 65% of the water in the body. The ECF contains about 35% of the water. Of the 35% of water in the ECF, 25% is interstitial fluid, 8% is found in blood plasma and lymph, and 2% is transcellular fluid.
A typical young adult male is 55% - 60% water. For a 150lb (70 kg) male, the total body water is about 40 L. Women average slightly less. Obese and the elderly can be as little as 45% water.
