What are the contents of human urine?

True..but the contents also depend on what you had recently...(ex. alcohol , medicine etc..

No.\nHowever, many creams and medications contain urea, which is one of the main components of urine. Urea is not urine, however.\n\nThat is probably where your friend got their information from.

Proteinuria\n\nHealthy kidneys take wastes out of the blood but leave in protein. Impaired kidneys may fail to separate the protein from the wastes. Proteinuria means protein in the urine, and it is a sign of poor kidney function. If your urine makes foam in the toilet, it may contain high levels of protein. Your doctor may test for protein using a dipstick in a small sample of your urine taken in the doctor's office. The color of the dipstick indicates the presence or absence of proteinuria. For a more precise measurement, you may need to collect urine for 24 hours.

Where did you find such value? If it is in the urinalysis, how was it reported. Epithelial cells in the urine can be normal or a sign of erosion. Three epithelial cells in the urine is not bad. A +3 value is too many and may be cause for alarm. Three epithelial cells per high power field (hpf) may mean nothing if not correlated with other abnormal findings. Watch out for RBC/rbc/red blood cell, WBC/wbc/white blood cell, and pus cells.

B. the bloodstream\n\nThe glomerular filtrate is nearly - all resorbed in the tubules; only a teeeeeny % of the water, glucose, human serum albumin and salts are excreted in urine.

There is no way to know.  When people are asked questions about behavior that is widely disapproved of, a large percentage of people lie.\n\nIt would be nice to be able to chemically analyze pool water and get a definitive answer.  That won't work, though, because urine and sweat have almost exactly the same chemical composition.  \n\nYou may take comfort in the fact that urine is sterile when it is passed.  White blood cells roam the surface of your bladder consuming any microbes they encounter.  Although urine is a good medium for bacterial growth, the chlorine in pool water keeps the bacteria from flourishing.  You should be more concerned about not washing your hands before you eat.

All of the liquids in the body go into the bloodstream. While there, they flow through the kidneys. These filter out all of the things that shouldn't be in the blood, and the wastes go through the ureters into the bladder. The bladder collects it until it is more than half full. Then it sends a signal to the brain that tells you you need to go to the bathroom where the pee comes out through the urethra.

A lot, actually. The kidney and the small and large intestines are the most well-known ones. But your skin actually does it's share of excreting waste from your body too. And so do your lungs. Carbon dioxide is a waste product after all.

There is a breakdown product of hemoglobin (a major component of red blood cells) called bilirubin.  Bilirubin is eliminated through urination and defecation but it breaks down into the other products.  One of the products is yellow (so that's y pee is yellow)....the other product is brown (and that's y poop is brown)

Depending on the size of the bladder, elasticity, and so on, the bladder can hold an estimated 600-1000 ml of urine. But as I said, all bladders are different.

I know the answer. The total quantity of ATP in the human body is about 0.1 mole. The energy used by human cells requires the hydrolysis of 200 to 300 moles of ATP daily. This means that each ATP molecule is recycled 2000 to 3000 times during a single day. ATP cannot be stored, hence its consumption must closely follow its synthesis. On a per-hour basis, 1 kilogram of ATP is created, processed and then recycled in the body.

The yellow is from the breakdown of old blood cells.  It is a compound called urobilirubin and your kidneys pee it out.  If your urine is clear, it is not necessarily a sign that you are well hydrated, but a sign that there is not much urobilirubin in the urine.  Most of the time it's because the urine is dilute by a lot of water, though.

Urine is yellow because of impurities and ammonia. To make urine clear, drink heaps of water. To increase semen quantity, eat lots of fruit and vegatables, and drink lots of water. To satisfy a woman sexually, have sex with her =P

The excretory system is responsible for removing waste materials from the body. The primary organ for excretion is the kidney which releases waste in the form of urine. Another organ of excretion is the skin which removes waste from the body in the form of sweat. Another organ of excretion is the lung. The lung is responsible for removing Carbon dioxide and water vapor. And the last member of the said system is the large intestine. The large intestine is responsible for removing undigested food from the body. The process of doing so is called elimination rather than excretion.

urine contains urea and ammonium ions which are poisonous, but only if you drank loads of it. poo is fine. eat all the poo you like, gorillas do...
