Total body water (TBW) is about 60% of body weight in men (ranging from about 50% in obese people to 70% in lean people) and about 50% in women. Almost two thirds of TBW is in the intracellular compartment (intracellular fluid, or ICF); the other one third is extracellular (extracellular ...Fluid, molecules, and ions flow across physical barriers between the fluid compartments. The physical barrier separating the intracellular fluid compartment (i.e., cytoplasm) and the interstitial fluid is the cell plasma membrane. The capillary endothelium is the physical barrier that separates the interstitial fluid from plasma.The main difference between interstitial fluid and extracellular fluid is that interstitial fluid is the fluid between cells in tissues and organs, whereas extracellular fluid is the fluid outside the cells in the body. Extracellular and interstitial fluids are two distinct components in the body’s fluid compartments. Key Areas Covered. 1.Interstitial Fluid. Interstitial fluid is a form of extracellular fluid which is found in the space between cells in most biological tissues. It is a bridge between the blood and tissue cells and helps regulate the exchange of nutrients, water and waste between these two different compartments, thus playing an important role in maintaining homeostasis.The definition of edema is a swelling due to the expansion of interstitial fluid volume in tissues or an organ.
