Potassium is an essential mineral that is needed by all tissues in the body. It is sometimes referred to as an electrolyte because it carries a small electrical charge that activates various cell and nerve functions. Potassium is found naturally in many foods and as a supplement.

For more information, see Changes to the Nutrition Facts Label. Your body needs a small amount of sodium to work properly, but too much sodium can be bad for your health. According to the Dietary Guidelines for Americans , diets higher in sodium are associated with an increased risk of developing high blood pressure , which is a major cause of stroke and heart disease.

Renal Diet

People w ith compromised kidney function must adhere to a renal or kidney diet to cut down on the amount of waste in their blood. Wastes in the blood come from food and liquids that are consumed. When kidney function is compromised, the kidneys not filter or remove waste properly. Following a kidney diet may also help promote kidney function and slow the progression of complete kidney failure. A renal diet is one that is low in sodium, phosphorous, and protein. A renal diet also emphasizes the importance of consuming high-quality protein and usually limiting fluids.

Potassium is the main intracellular ion for all types of cells , while having a major role in maintenance of fluid and electrolyte balance. It is found in especially high concentrations within plant cells, and in a mixed diet, it is most highly concentrated in fruits. The high concentration of potassium in plants, associated with comparatively very low amounts of sodium there, historically resulted in potassium first being isolated from the ashes of plants potash , which in turn gave the element its modern name. The functions of potassium and sodium in living organisms are quite different. Animals, in particular, employ sodium and potassium differentially to generate electrical potentials in animal cells, especially in nervous tissue. Potassium depletion in animals, including humans, results in various neurological dysfunctions. Characteristic concentrations of potassium in model organisms are: mM in E.

Potassium in biology

Potassium and sodium are electrolytes needed for the body to function normally and help maintain fluid and blood volume in the body. However, a person can get high blood pressure by consuming too much sodium and not enough potassium. Vegetables and fruits, such as potatoes, tomatoes, leafy greens, sweet potatoes, beans, and bananas; dairy products, such as yogurt; and seafood, such as salmon and clams, are good sources of potassium. One gram of salt sodium chloride equals milligrams of sodium. Section Navigation. Facebook Twitter LinkedIn Syndicate. The combination of consuming more sodium and having too little potassium in your diet is associated with higher blood pressure.

A primary care approach to sodium and potassium imbalance

Potassium is one of the main blood minerals, or electrolytes, essential to both cellular and electrical function. Along with sodium, potassium regulates the water balance and the acid-base balance in the blood and tissues, and plays a critical role in the transmission of electrical impulses in the heart. The active transport of potassium into and out of the cells is crucial to cardiovascular and nerve function. When potassium enters the cell, it instigates a sodium-potassium exchange across the cell membrane.

Он опять перегнул палку. Его план не сработал. Почему она не хочет ему поверить. Росио подошла к нему еще ближе. - Я не знаю, кто вы такой и чего хотите, но если вы немедленно отсюда не уйдете, я вызову службу безопасности отеля и настоящая полиция арестует вас за попытку выдать себя за полицейского офицера.

Это смертельная ловушка. Если даже он выберется на улицу, у него нет оружия. Как он заставит Сьюзан пройти вместе с ним к автомобильной стоянке. Как он поведет машину, если они все же доберутся до. И тут в его памяти зазвучал голос одного из преподавателей Корпуса морской пехоты, подсказавший ему, что делать. Применив силу, говорил этот голос, ты столкнешься с сопротивлением.
