Less fluid in the body: In older people, the body contains less fluid. They help maintain the acid-base balance in the body. These two electrolytes have many functions including maintaining nerve and muscle function.

Potassium enters the cell more readily than does sodium and instigates the brief sodium-potassium exchange across the cell membranes. It is mandatory to procure user consent prior to running these cookies on your website. In "Biological Psychology," James W. Kalat writes that the result of this process is that sodium ions are more concentrated outside of your cell membranes while potassium ions are more concentrated inside cell membranes. Sodium and potassium are two essential elements that are needed to regulate blood pressure and play an active part in many bodily functions. At any given time, three sodium ions are allowed inside a cell. Our site includes quite a bit of content, so if you're having an issue finding what you're looking for, go on ahead and use that search feature there! Potassium and sodium ions generate power for your body. Functions: Potassium is very important in the human body. Terms of Use Well, we're looking for good writers who want to spread the word. This is the action potential. Potassium activates nitric oxide to reduce pressure in the arteries, and thus, lowers the risk of hypertension. Neurons use ions to communicate. Dr. Richard Moore, MD, PhD, in his book The High Blood Pressure Solution: Natural Prevention and Cure with the K Factor, showcases that eating according to the K factor can protect against hypertension, strokes, and untimely death. When drawing in sodium ions, the cell is positioned to attract ions shaped like sodium ions. LIVESTRONG is a registered trademark of the LIVESTRONG Foundation. They communicate information to perform important tasks such as regulating your body temperature or flexing muscles. Potassium and sodium are two of the most important ions in your nervous system. Potassium ions are considered important in brain signaling. Potassium and sodium ions act as power generators inside the cells of your body. Potassium and sodium are electrolytes needed for the body to function normally and help maintain fluid and blood volume in the body. Potassium and sodium ions act as power generators inside the cells of your body. Only 45% of body weight is fluid in older people, compared with 60% in younger people. Sodium and potassium are two important elements that play a vital role in the metabolic processes in the human body. This website uses cookies to improve your experience while you navigate through the website. Maintaining the ratio between these two elements is key to good health. Copyright Policy Sodium and potassium have opposite effects on the heart. When they do, the in and out flow of potassium and sodium ions creates polarization and reverse polarization. If suffering from kidney diseases, adrenal exhaustion, or hypertension, increasing potassium intake should be avoided. This maintains the electrical charge. When a simulated neuron makes a request, sodium ions shoot like arrows into your cells, creating an explosion of energy. Energy is derived from pumping sodium outside the cell, where it becomes concentrated, wanting to push its way back in. Nerve impulse involves not only sodium, but also potassium. Sodium ions move first because of the uneven concentration between sodium and potassium ions. This category only includes cookies that ensures basic functionalities and security features of the website. A healthy body will balance the potassium levels in the body, however, excessive fluid loss by vomiting, diarrhea, etc., can cause the loss of potassium in the body. But, there is also a danger for consuming too much sodium, … Other Functions of Potassium in the Body. , A decrease in blood sodium concentration, also called hyponatremia, can cause seizures, while low potassium levels in the bloodstream, or hypokalemia, can lead to heart problems. The cells in your body need electrolytes to transport and maintain electrical impulses. Different ions (sodium, potassium, calcium, magnesium etc) have different roles to play. However, a person can get high blood pressure by consuming too much sodium and not enough potassium. The regulation and maintenance of sodium and potassium levels in and outside cells is very important for the normal functioning of the body. Eventually, the ions settle down and return to resting potential. As discussed by nutrition professors Michelle McGuire and Kathy Beerman, authors of NUTR, an afferent neuron at rest has actually favorably charged potassium ions inside the cell and is surrounded outside the cell by posit… Sydney Hornby specializes in metabolic disease and reproductive endocrinology. Potassium and sodium are electrolytes needed for the body to function normally and help maintain fluid and blood volume in the body. So, cutting down on salt and increasing your potassium intake will keep your heart and body healthy. Salt is a mineral that carries an electrical charge, called an electrolyte. Ions are electrically charged chemicals. The K factor is defined as a sodium-to-potassium ratio of at least one to four. and Because potassium is required for maintaining sodium levels, and hence fluid balance, about 200 milligrams of potassium are lost from the body every day. Improper ratio may also cause kidney stones and osteoporosis. diagnosis or treatment. advertisements are served by third party advertising companies. The sodium-potassium pump is integral in maintaining the acid-base balance as well as in healthy kidney function. You should consult your physician/dietitian before changing your diet, especially if you are suffering from any medical condition. This website uses cookies to improve your experience. Adopting a lifestyle with salubrious dietary changes, coupled with exercising, can work wonders for the body. The Ketogenic Diet Is The Fat Burning Diet, Boost Your Immune System With the Right Diet. Writing for publication since 1995, Hornby has had articles featured in "Medical Care," "Preventive Medicine" and "Medical Decision Making.". Protein Data Bank; Sodium-Potassium Pump; David Goodsell; October 2009, McKinley O'Loughlin Human Anatomy; Animation: How the Sodium Potassium Pump Works; 2006, PARTNER & LICENSEE OF THE LIVESTRONG FOUNDATION. The sodium-potassium pump also responds to power requests from your nervous system. Ions of salt, potassium and chloride trigger muscle contractions and nerve impulses when they shift locations throughout cell membranes. The LIVESTRONG Foundation and LIVESTRONG.COM do not endorse The resting potential of a cell is the amount of energy available when a cell is at rest. For instance, if you want to move your fingers, your brain transmits a message to the muscles in your hand. Potassium eliminates sodium from the cells, and thus prevents accumulation of fluids in the cells. Neurons transmit that message. The pump is pivotal to the body's function. While we know that high salt intake increases blood pressure, high potassium levels lower blood pressure by relaxing the blood vessels. Each time this happens, an electrical charge is produced. Proper electrolyte balance is important for your blood, hydration and helps maintain other vital body functions. The sodium-potassium pump is necessary for the creation of the chemical battery or electrical potential gradient, that helps the transmission of nerve signals as well as contraction of muscles. We also use third-party cookies that help us analyze and understand how you use this website. Neurons are cells located throughout your nervous system. However, consult your physician before starting any new regime. Studies suggest that low potassium intake is the cause of almost 90 – 95% high blood pressure cases and strokes. According to a study published in the New England Journal of Medicine, researchers found that an increase of only 390 mg of potassium averaged daily, decreased the risk of a stroke by 40% over a period of 12 years, irrespective of blood pressure. Role of Sodium and Potassium in the Body The sodium-potassium pump is necessary for the creation of the chemical battery or electrical potential gradient, that helps the transmission of nerve signals as well as contraction of muscles. Often, more emphasis is laid on the intake of either one of these. This energy is used to remove acid from the body. It also helps regulate heartbeats.

To overcome this, an increased potassium intake is recommended, as more the potassium levels in the body, more amount sodium is extracted out.
