Section III. THE HUMAN LYMPHATIC SYSTEM
Between the cells of the body are spaces filled with fluid. This is the interstitial
(or tissue) fluid, often referred to as intercellular fluid. There are continuous exchanges
between the intracellular fluid, the interstitial fluid, and the plasma of the blood. The
lymphatic system returns to the bloodstream the excess interstitial fluid, which includes
proteins and fluid derived from the blood.
