Interstitial fluid
Interstitial fluid is a type of fluid in the body. It is found in the interstitial spaces or tissue spaces - the fluid-filled areas that surround cells. It makes up about 3/4 of all extracellular fluid. Its main purpose is provide cells with nutrients and assist the cells in waste removal.
Some components of interstitial fluid are plasmatic, lymphatic, intraocular, synovial, pericardial, intrapleural, peritoneal, and digestive fluids.
Interstitial Fluid Media
The distribution of the total body water in mammals between the intracellular compartment and the extracellular compartment, which is, in turn, subdivided into interstitial fluid and smaller components, such as the blood plasma, the cerebrospinal fluid and lymph
