Some potassium is also lost through the digestive tract and in sweat. Maintaining the ratio between these two elements is key to good health. Potassium is consumed in food and drinks that contain electrolytes (including potassium) and lost primarily in urine. It regulates the heartbeat, ensures proper function of the muscles and nerves, and is vital for synthesizing protein and metabolizing carbohydrates. Updated Updated 7 … Plus, potassium also aids you in balancing out the negative effects caused by sodium. Potassium is necessary for the normal functioning of all cells. Magnesium is necessary for the formation of bone and teeth and for normal nerve and muscle function. Role of Magnesium in the Human Body. Potassium Function in Human Body Electrolyte. It is found in especially high concentrations within plant cells, and in a mixed diet, it is most highly concentrated in fruits. Overview of Potassium's Role in the Body. Each of the minerals chemically attracts water to itself, thus assuring that optimal levels of hydration are maintained both inside human cells and outside the cells, in the extracellular spaces that surround them. An adult body contains approximately 25 g magnesium, with 50% to 60% present in the bones and most of the rest in soft tissues . Magnesium is the fourth most abundant cation in the body and the second most abundant intracellular cation after potassium . Hypokalemia: low serum potassium (deceases heartbeats and interferes with vital muscles such as those involved in respiration) 2. So, what is the specific role of potassium in the human body? Another is sodium. The intracellular-extracellular potassium ratio (K i/K e) largely determines neuromuscular tissue excitability [1]. Risk of low potassium levels. The functions and normal range values for these electrolytes are described below. . Many foods contain potassium. Potassium is one of the most important electrolytes in the human body, with others consisting of chloride, calcium, phosphorus, magnesium and salt. The most common electrolytes are sodium, potassium and chloride; other electrolytes include calcium, magnesium and phosphorus. Potassium is essential for the proper function of all cells, tissues, and organs in the human body. The nervous system helps to regulate the contractions of muscles. Many enzymes in the body depend on magnesium to function normally. Electrolytes are compounds that help perform electricity in your body. This change means that a slight loss of fluid and sodium, as can result from a fever or from not eating and drinking enough (sometimes for only a day or two), can have more serious consequences in older people. Potassium is an important mineral to the body and plays roles at both the cellular and electrical level. Your body needs potassium to: Build proteins; Break down and use carbohydrates; Build muscle; Maintain normal body growth; Control the electrical activity of the heart; Control the acid-base balance ; Food Sources. Shortly, they produce the necessary electricity that runs cells. Magnesium is an essential cofactor for a diverse metabolic reactions involving more than 300 enzymes within the human body . 98 percent of the potassium in the body is found inside the cells. You get them from foods and supplements. Sodium and potassium are two important elements that play a vital role in the metabolic processes in the human body.
