  2. Potassium in biology - Wikipedia

    en.wikipedia.org/wiki/Potassium_in_biology

    The sodium–potassium pump a critical enzyme for regulating sodium and potassium levels in cells. Potassium is the main intracellular ion for all types of cells, while having a major role in maintenance of fluid and electrolyte balance. [1] [2] Potassium is necessary for the function of all living cells and is thus present in all plant and ...

  3. Composition of the human body - Wikipedia

    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 ...

  4. Potassium - Wikipedia

    en.wikipedia.org/wiki/Potassium

    Potassium is the eighth or ninth most common element by mass (0.2%) in the human body, so that a 60 kg adult contains a total of about 120 g of potassium. [84] The body has about as much potassium as sulfur and chlorine, and only calcium and phosphorus are more abundant (with the exception of the ubiquitous CHON elements). [85]

  5. Mineral (nutrient) - Wikipedia

    en.wikipedia.org/wiki/Mineral_(nutrient)

    The five major minerals in the human body are calcium, phosphorus, potassium, sodium, and magnesium. [2] The remaining minerals are called " trace elements ". The generally accepted trace elements are iron , chlorine , cobalt , copper , zinc , manganese , molybdenum , iodine , selenium , [ 5 ] and bromine ; [ 6 ] there is some evidence that ...

  6. Potassium-40 - Wikipedia

    en.wikipedia.org/wiki/Potassium-40

    A 70 kg human body contains about 140 g of potassium, hence about 140g × 0.0117% ≈ 16.4 mg of 40 K; [7] whose decay produces about 3850 [8] to 4300 disintegrations per second continuously throughout the life of an adult person (and proportionally less in young children). [Note 3] [9]

  7. Electrolyte imbalance - Wikipedia

    en.wikipedia.org/wiki/Electrolyte_imbalance

    It is a common saying in human physiology that "cells are bags of Potassium floating in a sea of Sodium" Sodium and its homeostasis in the human body is highly dependent on fluids. The human body is approximately 60% water, a percentage which is also known as total body water. The total body water can be divided into two compartments called ...

    Can substitute for potassium (a biologically essential element) with possible adverse effects, [11] particularly if the substitution is of radioactive cesium, which was the primary biologically active isotope released in the 1986 Chernobyl nuclear disaster. [11] [35] chlorine: 17: 5a: Chlorine salts are critical for many species, including ...
