Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
Water is an inorganic compound with the chemical formula H 2 O.It is a transparent, tasteless, odorless, [c] and nearly colorless chemical substance.It is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent [20]).
HTO has a short biological half-life in the human body of 7 to 14 days, which both reduces the total effects of single-incident ingestion and precludes long-term bioaccumulation of HTO from the environment. The biological half life of tritiated water in the human body, which is a measure of body water turn-over, varies with the season.
Water – chemical substance with the chemical formula H 2 O. A water molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at ambient conditions , but it often co-exists on Earth with its solid state, ice , and gaseous state ( water vapor or steam ).
The usual way of adding water to a body is by drinking. Water also enters the body with foods, especially those rich in water, such as plants, raw meat, and fish. About 10% of human adult water intake comes as a by-product of metabolism. [20] The amount of this water that is retained in animals is affected by several factors.

Hexagonal water, also known as gel water, structured water, cluster water, [1] H3O2 or H 3 O 2 is a term used in a marketing scam [2] [3] that claims the ability to create a certain configuration of water that is better for the body. [4] The term "hexagonal water" refers to a cluster of water molecules forming a hexagonal shape that supposedly ...
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).
