In the anatomy of mammals, the urinary bladder is the organ that collects urine excreted by the kidneys prior to disposal by urination. Urine enters the bladder via the ureters and exits via the urethra.\n---------\nAnatomy\nThe urinary bladder is a hollow, muscular and distensible organ that sits on the pelvic floor (superior to the prostate in males). On its anterior border lies the pubic symphysis and, on its posterior border, the vagina (in females) and rectum (in males). The urinary bladder is normally capable of storing 1.1-1.3 liters of urine, but because it is made up of transitional epithelium it is able to stretch to volumes of even several litres.\n\nThe ureters enter the bladder diagonally from its dorsolateral floor in an area called the trigone. The trigone is a triangular shaped area on the postero-inferior wall of the bladder. The urethra exits at the lowest point of the triangle of the trigone\n--------------\nDetrusor muscle\nThe detrusor muscle is a layer of the urinary bladder wall, made up of smooth muscle fibers arranged in inner and outer longitudinal layers and a middle circular layer. Contraction of the detrusor muscle causes the bladdar to expel urine through the urethra. Problems with this muscle can lead to incontinence.

The kidneys filter the blood, produce urine, and reabsorb vital electrolytes.  The spleen destroys old blood cells and plays a part in the immune system.

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.

If you have had kidney stones, then that is what is probably causing this hematuria (blood in urine). Some other causes include:\n\nTrauma\nUrinary Tract Infections\nGlomerulonephritis\nNeoplasms esp., Renal Cell Carcinoma\nIgA Nephropathy\nHereditary Nephritis\nCoagulopathy\nCertain drugs can cause hematuria secondary to the papillary necrosis of the kidneys, eg, Non Steroidal Anti-Inflammatory Agents- aspirin, ibuprofen etc\n\nWhatever the case may be, it is undoubtedly essential for you to go and see your doc immediately. He will do the necessary tests to rule out any serious pathology. Better to be safe than sorry! Besides you need to take treatment, for whatever is causing the hematuria... delaying this wont help you in any way.

There are many ways in which these two systems work together to maintain homeostasis but let's keep it simple if we can...\nBy excretory system I imagine you are referring to the kidneys, ureter, bladder, etc. This system receives about a quarter of the blood volume from each stroke of the heart, and filters out the impurities and excess water from the bloodstream. By doing this the kidneys (along with the lungs) help to maintain the pH of the blood (maintain the acid to base balance.) If the pH varies too much then the person's life could be in danger. By removing excess minerals from the body the kidneys also prevent potential life-threatening problems from occurring. For example, if you have too much potassium in your body, even though it is necessary to have some, your heart could stop. \nBy removing excess water from the blood, along with producing certain hormones, the kidneys also help blood pressure from getting too high or low. A healthy heart and blood vessels also contribute to maintaining blood pressure by constricting and expanding the vessels, and by changing the rate of your pulse. Hope this helps some...

It's sounds like a urinary tract infection.  Get to your doctor.  An infection left unchecked and untreated can travel from your bladder to your kidneys or can get into your blood stream.  You need antibiotics.  See your doctor today, oh and take a urine specimen with you when you go.  Make sure you mention to your doctor the burning and the frequent urges for urination when the bladder is empty.

Well, on a space ship the water in urine actually is recycled, but the waste products are removed first.  No one wants to drink urea (the yellow part), but the water's just water.  It might seem weird to think about, but the water portion of urine is recycled on a global scale too.  When you flush the toilet, it goes to a sewage treatment plant, and then the treated sewage is dumped some where.  Eventually, the water evaporates, and then comes back in the form of rain.  Chances are that every molecule of the water you drink has been through the body of some person or animal somewhere at least once.\n\nAs for recycling feces, it's not practical.  The waste that's excreted is excreted for a reason.  There's little or no valuable nutrients left, and it's teaming with harmful bacteria.  However, like water, the atoms in feces are recycled.  Wherever it ends up, bacteria and fungi will decompose the compounds in feces, and they will end up in the soil.  Some of these atoms in the soil are then absorbed by plants.  So there are probably former feces atoms in the cocoa beans that were used to make your brownies.  Not quite as direct as you were imagining, but on some level it does happen.

Urine theraphy isn't a sin, but it doesn't work actually, it's all myth. It is full of amonia and uric acid and basically, urine is the liquid that comes out of your body, after your organs filter your system. So basically, urine isn't the best thing to try out.

It is filtered and the impurites are removed. It is 'tested' by the kidneys for perfect balance and then fluid and the other extra things are removed. For example if you took a medication or ate alot of beets, your urine changes color because the kidney removed the beet coloring and the medication that wasn't used by your body before it got there. The kidneys also help to control your blood preasure.

urine is really excreted.\nThis occurs in the kidneys.\nThe Glomeruli are basically filters which don't let out blood cells or proteins. However the product of this filtration is then regulated by a series of tubules within the kidneys called the proximal and distal convoluted tubules and between them the loop of Henle. These control the resorption of important nutrients like glucose as well as the salt balance of the urine. They ensure the excretion of waste products like urea. This salt egulation is in turn regulated by the renin angiotensin/aldosterone sequence ofhormones that regulate sodium and potassium in the body. This is to ensure HOMEOSTASIS: a balanced blood plasma.\nThe end product, urine is excreted through the kidneys into the bladder and hence out of the body.\nKidneys, therefore do not just excrete urine: they purify plasma.

do u mean liver cirrhosis? if the liver is damaged it doesnt work properly so substances that are usually removed by the liver pass into the blood stream....the kidney then has to filter these extra substances and can get damaged by excesses, much of which comes out in the urine.  also in severe liver failure the kidneys will become affected and in turn they will fail too

uuuuuuuummmmmmmmmm........\nmaybe theres this vein or cell or something that conects your bladder 2 your eyes, and when your bladder is emptied, your eyes are 2!!!!\n\nI dunno, just a thought
