What is the role of sodium ions in the functioning of kidney?

I don't know exactly what role they have but are you talking about what process do tey go through or the actual function of the kidney. Like it's ability to filter. If thats the case then sodium is just a ion the is filtered throughout parts of the nephron (functional unit of the kidney).  You asked the question like how it would sound if someone said what role does food have in the stomach. As pertaining to actual functioning of the kidney I don't know. Some parts of the nephron are more permeable to certain substances. The loop of henle is the site of loop diuretic action and that affects water loss. Water loss and ion regulation is a function of the kidney.

It's not really a question of what's effected - its more of a progression.  The ones to go first really depend on what is causing the loss in homeostasis.  Then these first organs may effect other organs.  For example, if potassium is off - it will effect the heart.  However, if kidneys fail for some reason and affect the balance of ions in the body, then they will eventually affect other organs.  So it is a tough question to answer, but any organs may be affected and it will depend on what the cause is.  \nMostly the big organs you worry about are heart, kidney, liver, CNS (brain), lungs.

What is kidney failure? \n\nThe function of the kidneys is, among other things, to get rid of the waste products that result from the body's metabolism. \n\nOne of the major by-products of the metabolism of protein (muscle) is urea. The kidneys remove the waste products by extracting them from the blood and sending them along the ureter to the bladder, from where they are excreted in the urine.\n\nIf the kidney function fails, the waste products accumulate in the blood and the body. The term for this build-up is azotaemia. \n\n \nTerm watch\n\nAzotaemia is the build up of waste products that accumulate in the blood and the body when the kidneys fail to function. \n \n \nVery mild levels of azotaemia may give little or no symptoms, but if the kidney failure continues then symptoms will start to appear. \n\nIf the kidney (or renal) failure is of sufficient degree to cause symptoms, it is called uraemia.\n\nWhat causes renal failure? \n\nRenal failure can happen rapidly - over days, weeks or months (acute renal failure) or slowly over a period of years (chronic renal failure).\n\n\nAcute renal failure\n\nThis may occur with any serious illness or operation, particularly those complicated by severe infection. If the blood supply to the kidneys is reduced considerably from blood loss, a fall in blood pressure, severe dehydration or lack of salt, then the kidneys may be damaged. If this problem lasts long enough there can be permanent damage to the kidney tissue.\n\nSudden blockage to the drainage of urine from the kidney can cause damage. A kidney stone is a possible cause of this. \n\nAcute kidney damage can occur as a rare side effect of some medications and other rare conditions. \n\n\nChronic renal failure\n\nThere are many causes of chronic renal failure, including inflammatory conditions affecting the kidney tissue, as a complication of long-standing diabetes mellitus (sugar diabetes), chronic blockage to the drainage of the kidneys and as a result of certain inherited conditions such as polycystic kidney disease. Often, the cause has occurred many years earlier and cannot be identified.\n\n\nWhat are the symptoms?\n\n\nAcute renal failure\n\nHere the symptoms are largely those of the condition causing the kidney failure, such as:\n\n\nblood loss, causing a drop in blood pressure.\n\n\nvomiting and diarrhoea, causing dehydration.\n\n\ncrush injuries. If large amounts of muscle are damaged there is a release of toxic protein substances that are harmful to the kidneys.\n\n\nSudden blockage of urine drainage.\n\n\n\n\nChronic renal failure\n\nThe damage to the kidneys is usually 'silent' and not noticed at an early stage. It may be discovered incidentally from blood or urine tests done for other reasons. High blood pressure very commonly occurs with it. Symptoms are uncommon unless kidney failure is far advanced, when any of the following may be present:\n\n\ntiredness\n\n\nitching\n\n\nloss of appetite\n\n\nnausea and vomiting\n\n\nbreathlessness \n\n\nfluid retention, shown as ankle swelling (oedema)\n\n\nweakness.\n\n\n\n\nHow is renal failure treated? \n\n\nAcute renal failure \n\nMost causes of acute renal failure can be treated and the kidney function will return to normal with time. Replacement of the kidney function by dialysis (artificial kidney) may be necessary until kidney function has returned.\n\n\nChronic renal failure\n\nChronic kidney damage is usually not reversible and if extensive, the kidneys may eventually fail completely. Dialysis or kidney transplantation will then become necessary.\n\nChronic kidney failure is a serious condition which needs urgent attention when it is diagnosed, but the kidney damage is usually 'silent' and not noticed at an early stage.\n\nOccasionally it may be possible to identify and treat the cause of the renal failure itself. More commonly the treatment has to be non-specific. In all cases, careful blood pressure control is extremely important in slowing the pr

Intake and output is an easy way to distinguish kidney function.\n\nKidney function tests are vitally important, as when someone is in the hospital, if the kidneys quit; the person could die quickly.

The correct sequence is (B).  Here's a numbered explanation:\n\nUnder normal conditions, potassium ions leak out of a cell faster than sodium ions leak in; as a result, a 'resting' cell membrane will have a negative potential.  Some stimulus may then cause a depolarization (movement toward neutral potential) in some small part of the membrane [4] -- this is the beginning of the action potential process.  Depolarization allows sodium ions to flood through the cell membrane [6], driving the membrane into positive potential [7].  At a certain point, the sodium channels shut down in response to the change in potential [1], and the flood reverses -- now potassium ions diffuse out of the cell in larger numbers [2].  Eventually, the sodium channels reach their normal state again [3].  The potassium channels also calm down, but just like the sodium ions before, they've gone too far, resulting in hyperpolarization of the membrane (or what is also called the 'undershoot,' because the potential goes more negative than its resting value) [5].

If I remember right, the crystalline structure of the salt breaks down, and the Na and Cl ions move freely in the water, dissolving into the water.\nSince the salt breaks down into free ions, that explains why salt water is such a good electrical conductor.

" Alcohol can cause all kinds of damage to the kidneys.  These effects can range from cell damage and enlargement of the kidneys to alcohols’ impact of the various hormones that control kidney function.  Alcohol creates an ionic imbalance in the body that can negatively affect many metabolic processes" "Alcohol destroys this delicate balance of the ions and water in the body by altering the filtering ability of the kidneys.  Although the exact mechanisms for how alcohol changes the kidney’s ability to function are not clearly known, the changes in ionic concentrations have been studied in humans and in animals for many years.  Kidney complications are even greater if a person has also been diagnosed with liver damage due to alcohol consumption."\nComplications of Alcohol – Kidney Link

The kidneys are always trying to maintain homeostasis - keeping the water to mineral ratio in your blood constant.\n\nIf you stayed inside and drank lots of tea, you will have a big increase in water in your blood, while the amount of minerals stays the same. Your kidneys would then remove lots of water from your blood and keep the minerals, to return the concentration of minerals back to normal. (You'll urinate a lot)\n\nIf you used up a lot of your body's water by sweating and then not replenishing it, the mineral concentration would be much higher. The kidneys will try to return the concentration back to normal by letting out a lot of minerals but not a lot of water (You won't urinate as much, and when you do, it will be very concentrated)

For individuals who are sodium-sensitive, an increased intake of sodium may contribute to high blood pressure . Therefore, people with high blood pressure may be advised to reduce sodium intake; all patients with high blood pressure should discuss this issue with their doctor. Reducing sodium can also reduce the side effects from certain prescription medications.\n\nIn addition, sodium may lead to fluid retention in patients with congestive heart failure , cirrhosis , or kidney disease . These patients should be on strict sodium-restricted diets as prescribed by their doctor.

Sodium can cause the body to retain water.If your kidneys can't eliminate enough sodium, the sodium starts to accumulate in your blood. Because sodium attracts and holds water, your blood volume increases. Increased blood volume, in turn, makes your heart work harder to move more blood through your blood vessels, increasing pressure in your arteries. Certain diseases such as congestive heart failure, cirrhosis and chronic kidney disease can lead to an inability to regulate sodium.\n\nYour body needs some sodium to function properly. \nIt helps maintain the right balance of fluids in your body \nAssists in transmission of nerve impulses \nIt influences the contraction and relaxation of muscles
