Body Fluids

A significant percentage of the human body is water, which includes intracellular and extracellular fluids.

The major body fluid compartments include: intracellular fluid and extracellular fluid (plasma, interstitial fluid, and trancellular fluid).

The composition of tissue fluid depends upon the exchanges between the cells in the biological tissue and the blood.

Movement of fluid among compartments depends on several variables described by Starling's equation.
