Question

Quizplus · Accepted Answer

Extracellular water is found in three subcompartments: (1) intravascular water (plasma), (2) interstitial water, and (3) transcellular fluid. Intravascular water makes up approximately 5% of the body weight. Interstitial water is water in the tissues between the cells. It makes up approximately 15% of the body weight. Transcellular fluid is quite small in proportion to plasma and interstitial fluid.
