In 1807, a man by the name Sir Humphrey Davy discovered Potassium in London, England (Barbalance, Environmental-Chemistry). Potassium was the first element to be found through electrolysis (Softschools). Electrolysis is the chemical decomposition produced by passing an electric current through a liquid or solution containing ions. In addition to electrolysis, thermal methods are also used to produce potassium. Thermal method is a mixture or a reactant that I measured as a function of temperature

Potassium is freely filtered in the glomerulus. Two thirds of the potassium is reabsorbed along the proximal tubule. The potassium concentration in the proximal tubule is roughly equal to that of plasma. In the descending limb of Henle a small amount of potassium is secreted into the luminal fluid and is reabsorbed by the ascending limb of Henle. The concentration of potassium is the distal convoluted tubule is now lower than the concentration in the plasma. The connecting tubule and cortical connecting
Potassium is an element on the periodic table that is symbolized by the letter K. The atomic number of this element is 19. At room temperature this element is a solid. Potassium can be found in two forms: either pure or compounds. Pure potassium is described as a soft silvery-white alkali metal that oxidizes rapidly in air and is very reactive in water However, Potassium forms many compounds such as Potassium chloride, which is the most common potassium compound (Gagnon, 1). This form of Potassium

difference between potassium and sodium was not discovered until the 18th century. "Vegetable alkali" also known as potassium carbonate came from the earth. "Mineral alkali" also known as sodium carbonate came from wood ashes. Early chemists did not recognise that these were two different chemical compounds. Sir Humphry Davy discovered potassium in 1807 in England, by isolating it using electrolysis. Potassium was the first metal to be isolated by using electrolysis. The name potassium originated from
fluid. The common cation that being measured are sodium ion and potassium ion, but potassium ion usually not included within the calculation due to very low amount within human body fluid (Emmett and Narins, 1977, pp. 38). The common anions used in the calculation of anion gap are chloride ion and bicarbonate ion. The calculation of anion gap as following: [(Na2+ + K+) − (Cl- + HCO3- )] (Wilson, 2012, p. 907) Usually, potassium ion is not included due to low concentration and stable amount. Therefore
Potassium Potassium is a vital element in the human body. Potassium had never been distinguished between sodium until the eighteenth century. Before potassium was recognized as an element, potassium carbonate was mixed with animal fat to make soap. It was discovered by Sir Humphrey Davy in England, in 1807. Sir Davy was able to isolate potassium using electrolysis. Potassium was the first metal isolated by this procedure. Today, it is still not found free in nature. It is obtained by electrolysis
is important for your body to function appropriately. Electrolytes are electrically charged minerals, negative or positive, and run throughout the body’s fluids, blood, and urine. The major electrolytes of the body are Na+ (sodium), K+ (potassium), Cl– (chloride), Ca2+ (calcium), H+ (hydrogen), HCO3– (bicarbonate), and phosphates; these electrolytes can be found in the food and drinks we consume everyday. They are responsible for many body processes such as the transport of water and other fluids
Fluids and Electrolytes Homeostasis is the body’s way to maintain internal stability. Cells require certain conditions to function properly. The ability to produce energy is key to life. Animals eat food and take in liquids that the body breaks down to be used by cells to produce energy. Oxygen is required by cells to convert carbohydrates or sugars into energy. Fluids are responsible for the transportation of nutrients to cells and the transportation of waste products of energy production out of
faster. Plants need twenty essentail elements to help them grow. Plants make carbohydrates. A plant needs nitrogen, phosphorus, potassium, calcium, sulfur, and magnesium the most to grow healthy. Most soils naturally contain enough trace elements for field crops, but such elements must be added when certain fruits and vegetable plants are grown. Nitrogen, phosphorus, and potassium are the top three elements needed in plant growth. Legumes are plants which absorb nitrogen gas from the air and bring the
the importance of consuming high-quality protein and usually limits fluids. Some patients may also need to limit potassium and even calcium” (Nephcure). Throughout the course of this paper various aspects are addressed. these include: the role of the kidneys, the importance of professional guidance, the reasons why people follow a renal diet, monitoring sodium intake, monitoring potassium intake, monitoring phosphorus intake, protein consumption, and fluid control. The Role of the
balance of many key substances, including glucose, urea, sodium, amino acids, chloride and potassium to name just few. According to …… there are specialized proteins called transporters located on the membranes of the various cells of the nephron. These proteins aid in active transport of some of the larger ions, others are reabsorbed through passive diffusion. Many of these ions including glucose, potassium and chloride are main components of other functions in the other systems in the body. The

When I was working as a bedside nurse in the Emergency Department, in one of my duties I was not satisfied with the treatment plan made by a resident doctor for XYZ patient. He entered intravenous KCL (potassium chloride) for the patient. The purpose of that medication and its dose for that patient was not clear to me. I assessed patient history and came to know that a middle aged patient came with the complaint of loose bowel movements, vomiting, and generalized weakness. His GCS (Glasgow comma
would signify that we are viewing ECF. Just the opposite, if the fluids are on the inside, we can conclude it is ICF. If we were to look at these fluids in-depth, intracellular fluids are high in potassium and magnesium and low in sodium and chloride ions, whereas extracellular is mostly sodium and chloride. Moreover, water moves inside and around the cell by osmotic pressure within each compartment and pulls fluid from one area to the other. The level of osmotic pressure remains approximately the
relative hypovolemia Hypovolemia is the decreased of blood volume related to extracellular fluid volume insufficiency. Extracellular volume is determined by the total amount of sodium and water when osmolality is normal. Visible loss of sodium, chloride and total body water due to increased fluid loss such as diarrhea, vomiting and polyuria or inadequate fluid intake is called actual hypovolemia. When the water within the body is displaced not lost, from the intravascular space to the interstitial
What is Potassium? Potassium (K+) is an important mineral the body needs to maintain and regulate many functions in the body. It is essential to life because it helps balance body water, regulate blood pressure, maintain heart function, and facilitate various cellular and tissue functions. Its function inside the cells is influenced by it positive electrical charge, which makes it a cation and an electrolyte, or a substance that regulates the flow of molecules, particularly water, across cell membranes

using various drugs in an isolated setting. The computer program entitled “Effects of Drugs on the Frog Heart” allowed experimental conditions to be set for specific drugs. The different drugs used were calcium, digitalis, pilocarpine, atropine, potassium, epinephrine, caffeine, and nicotine. Each of these drugs caused a different electrocardiogram and beats per minute reading. The calcium-magnesium ration affects “the permeability of the cell membrane”(Fox). When calcium is placed directly on
