![]() Together these fluids account for about 20 percent of the body weight, or. The relationship between the intracellular fluid compartment, interstitial fluid, and plasma can be seen in this figure. All the fluids outside the cells are collectively called the extracellular fluid. Note that this figure only demonstrates the relative sizes of body fluid compartments and does not provide any information regarding how these compartments are related to one another. Your brain and kidneys have the highest proportions of water, which composes 8085 percent of their masses. In adult women, the total fluid volume is approximately 55% of the total body weight. The average volume of plasma in the average (70-kilogram or 150-pound) male is approximately 3.5 liters (0.77 imp gal 0.92 U.S. 2 3 The exact percentage of fluid relative to body weight is inversely proportional to the percentage of body fat. The total body water is distributed primarily between 2 compartments, namely, extracellular fluid (ECF) and intracellular fluid (ICF) compartments. compartments account for 40 and 60 percent of total body water. In lean healthy adult men, the total body water is about 60 (6067) of the total body weight it is usually slightly lower in women (52-55). interstitial fluid is fluid in which cells are bathed. In adult men, the total fluid volume is approximately 60% of the total body weight. Pure water loss reduces the size of each compartment proportionately (Panel B). extracellular fluid (ECF) (1/3 of TBW) which is composed of. The extracellular fluid (ECF) compartment is further subdivided into the intravascular compartment and the extravascular compartment. All percentages shown in this figure refer to the percentage of the total body fluid volume in an adult human being. Approximately 33 of the total body fluid (or 20 of total body weight) is in the extracellular fluid (ECF) compartment. Transcellular fluid is found in small amounts in specialized compartments (e.g., cerebrospinal fluid, intraocular fluids, inner ear fluids, pericardial fluid, peritoneal fluid, synovial fluids, etc.). Interstitial fluid is the fluid that directly bathes the cells and tissues in the body. The intracellular compartment consists of all the fluids inside cells whereas the extracellular compartment consists of all the fluids outside of cells. Ingested foods and liquids (preformed water). In our body, water is distributed in two major fluid compartments: the intracellular and extracellular compartments. ![]() This compartment can be further subdivided into the interstitial fluid (~25% of total body fluid volume), plasma (~7% of total body fluid volume), and transcellular fluid (~1% of total body fluid volume). Water is the main component of all body fluids making up 45-75 of the total body weight. The extracellular fluid compartment makes up approximately 33% of the total volume of body fluids. This compartment holds approximately 67% of the total volume of body fluids. The intracellular fluid compartment contains the fluid that is present in the cytoplasm of all cells of the body. This fluid is distributed between blood plasma, interstitial fluid, and intracellular fluid with the following proportions: Body Fluid Compartment: Proportion (%) of Total Body Water (TBW): Blood Plasma 6.6 Interstitial Fluid 33.0 Extracellular Fluid (ECF) 26.4 Intracellular Fluid 67.0 67.As shown in other figures for men and women, body fluids are located in two main compartments: intracellular fluid (ICF) compartment and extracellular fluid (ECF) compartment. Isotope-dilution techniques are briefly discussed and representative normal values for the various compartments according to. For a typical 70 kg person, approximately 42 kg of this weight is water (which is equivalent to a volume of approximately 42 L of water). The following body fluid compartments are described: total body water (TBW), extracellular fluid (ECF), intracellular fluid (ICF), transcellular fluid TCF), plasma volume, red cell volume and interstitial fluid volume. ![]() about 20 percent of the body weight, or about 14 liters in a 70kilogram man. ![]() The fluid of each cell contains its individual mixture of. About 70 of an infants body weight is water. discussing average body fluid compartments, we should realize that variations exist, depending on age, gender. ![]() In an average adult male total body water is about 60 and the corresponding figure for an adult female is 50. Background Information: Body Fluid Compartments The human body is made up of roughly 60% water with dissolved ions in various body fluid compartments. So in lean people about 65 of the body weight is water and for fat people this is about 45. ![]()
