The adult human body averages ~53% water. [7] This varies substantially by age, sex, and adiposity. In a large sample of adults of all ages and both sexes, the figure for water fraction by weight was found to be 48 ±6% for females and 58 ±8% water for males. [8]
In physiology, body water is the water content of an animal body that is contained in the tissues, the blood, the bones and elsewhere. The percentages of body water contained in various fluid compartments add up to total body water (TBW). This water makes up a significant fraction of the human body, both by weight and by
In lean healthy adult men, the total body water is about 60% (60–67%) of the total body weight; it is usually slightly lower in women (52–55%). [2] [3] The exact percentage of fluid relative to body weight is inversely proportional to the percentage of body fat. A lean 70 kg (150 lb) man, for example, has about 42 (42–47) liters of water ...
The human body is the entire structure of a human being. ... The adult male body is about 60% total body water content of some 42 litres (9.2 imp gal; ...
The human body and even its individual body fluids may be conceptually divided into various fluid compartments, which, although not literally anatomic compartments, do represent a real division in terms of how portions of the body's water, solutes, and suspended elements are segregated. The two main fluid compartments are the intracellular and ...
Total body water in healthy adults is about 50–60% (range 45 to 75%) of total body weight; [1] women and the obese typically have a lower percentage than lean men. [2] Extracellular fluid makes up about one-third of body fluid, the remaining two-thirds is intracellular fluid within cells. [3]
Diagram depicting the distribution of total body water into percentages of intracellular and extracellular fluid. [19] Water content of a human body varies from 70-75% in newborns to 40% and less in obese adults, [20] an average value of 60% is suggested. [21] Within the body, water is classified as intracellular fluid or extracellular fluid.
A wide variety of body composition measurement methods exist. The gold standard measurement technique for the 4-compartment model consists of a weight measurement, body density measurement using hydrostatic weighing or air displacement plethysmography, total body water calculation using isotope dilution analysis, and mineral content measurement by dual-energy X-ray absorptiometry (DEXA).
