The figure for water fraction by weight in this sample was found to be 58 ±8% water for males and 48 ±6% for females. [3] The body water constitutes as much as 75% of the body weight of a newborn infant, whereas some obese people are as little as 45% water by weight. [4] This is due to how fat tissue does not retain water as well as lean tissue.
Body fluids, bodily fluids, or biofluids, sometimes body liquids, are liquids within the body of an organism. [1] 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 ...
The human body is composed of elements including hydrogen, oxygen, carbon, calcium and phosphorus. These elements reside in trillions of cells and non-cellular components of the body. The adult male body is about 60% total body water content of some 42 litres (9.2 imp gal; 11 US gal).
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.
Body composition. In physical fitness, body composition refers to quantifying the different components (or "compartments") of a human body. [1] The selection of compartments varies by model but may include fat, bone, water, and muscle. [2] Two people of the same gender, height, and body weight may have completely different body types as a ...
Edema (American English), also spelled oedema (British English), and also known as fluid retention, dropsy and hydropsy, is the build-up of fluid in the body's tissue, [1] a type of swelling. [4] Most commonly, the legs or arms are affected. [1] Symptoms may include skin that feels tight, the area feeling heavy, and joint stiffness. [1]
On Floating Bodies (Greek: Περὶ τῶν ἐπιπλεόντων σωμάτων) is a work, originally in two books, by Archimedes, one of the most important mathematicians, physicists, and engineers of antiquity. Thought to have been written towards the end of Archimedes' life, On Floating Bodies I-II survives only partly in Greek and in a ...
Human body weight is a person's mass or weight. Strictly speaking, body weight is the measurement of mass without items located on the person. Practically though, body weight may be measured with clothes on, but without shoes or heavy accessories such as mobile phones and wallets, and using manual or digital weighing scales .
