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.

urine contains urea, which is a nitrous acid that is digested out of the bloodstream. when the urea mixes with the toilet water, it foams.

Coffee has got caffine in it and that acts..that is as a colon simulant.  Caffine also makes your body produce more urine than normal so you pee more.  Also, when you use a stimulant like that, the stuff you're getting rid of also rids the boy of water weight.  You dehydrate yourself if you drink too much.

The solids that come out as feces come out of the end of the alimentary canal, which is one long tube from your mouth to your butt, so poop is basically everything you ate but couldn't digest.  Urine is a filtrate of the blood and is not directly connected to the intestines.  It is where much of the waste that the cells produce and dump into the blood is filtered and excreted, instead of just being left overs from meals like feces is.

The chances of a human getting ill from cat urine is practically nil.\nUrine is usually sterile in all species.  There are many products available to remove the odor and stain - usually sold in the pet section.

Pee a lot! Drink lots of water! That's the only way to clean it out quickly. There are also those pills that help you clean your system, but I don't know what they are called. I've never needed them.

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.

Your body will convert it into something it can store more easily: fat.\n\nThe only proteins you secrete in your GI tract are digestive enzymes and some immunological proteins.  You DON'T get rid of excess protein in your feces.  The only time you see protein in your urine is if there is something wrong with your kidneys.  You DON'T get rid of excess protein in your urine.  Note that urea is the by-product of protein metabolism, from--for example--protein being converted to fat, and is not itself protein (it is simply the nitrogenous part of the protein).\n\nYou need to exercise a little common sense here folks.  If you eat 5000 calories a day of 100 % protein, what do think is going to happen?  Do you think you're going to pee and poop out all those excess calories?  Of course not....

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)

Urine pH as measured by urinalysis has a normal range of about 4.5-8 with a pH of 6 being the average. Neutral pH is 7. Anything having a lower pH is acidic and anything with a higher pH is basic. \nUrine is actually a fairly good growth medium for bacteria and is sometimes used in labs for this pupose. However urine with a lower pH (more acidic) has been found to inhibit the growth of bacteria. \nUrine that is high in ammonia on the other hand with its higher pH (more alkaline or basic) has been found to impede the bodies immune responce to a UTI. In fact Proteus species of bacteria which is a common cause of UTIs produces a substance called urease which breaks down uric acid (an end product of nitrogen metabolism found in urine) into ammonia and carbon dioxide, thus causing the urine to become more basic. The ability of Proteus of produce urease increases its ability to cause pylonephritis (infection of the kidney as opposed to the blatter or ureters).\nTaking substances that will alter the pH of your urine however may have unforseen side effects. The pH of the urine helps determine what is and what is not filtered out of the blood by the kidney. Also altering the pH will have an effect of the formation of kidney stones. Certain particles will become "un-dissolved" at a higher pH and some at a lower pH. If enough of the particles come out of solution, you will get kidney stones. In fact the Proteus bacteria that cause the urine to become more basic are associated with an increase in kidney stones.\nI general however pH has very little to do with get or not getting a UTI. The urinary tract from the distal urethra up is mostly sterile and the few bacteria that do get into the urinary tract are usually flushed out when you urinate. Some bacteria however such as E. coli have molecules on thier outer membrane that can adhere to the urinary tract lining. It can do this reguardless of pH and pH in general has little effect on E. coli which is what causes about 85% of UTIs not contracted in a hospital. E. coli is found in the digestive tract and most UTIs are caused when the E. coli finds its way into the urinary tract. While in the digestive tract the E. coli has had to endure the extremely acidic pH of the stomach and the very basic pH of the small intestine.\nMost bacteria that cause UTIs are from the digestive tract. Often they are aided in migration to the urethra by sexual intercourse. The use of spermicides is associated with an increase in UTIs because the protective bacteria of the vagina are killed by the spermicide and this leave the vagina vulnerable to colinization by UTI causing bacteria.\nAlso some women are genetically predisposed to UTI because they have more adhesion molecules on their vaginal walls.\nCranberry juice is helpful in preventing UTI. Studies have shown that cranberry juice inhibits the ability of bacteria to adhere to the urinary tract.\nIf recurrent UTIs are a problem you may want to speak to you doctor about methanamine. It is used to prevent UTIs especially those caused by E. coli which is the most common cause of UTIs.

Urine is water and toxins that your body needs to get rid of.    There is no bacteria or germs in it, so it can't harm you in that way.  The toxins can't be too good for you though.  I would suggest something from your pharmacy, or a homeopathic method if you hate corporate medicine.\n\nIf you're going to pee in the shower aim for the drain. :-)

Hello\n\nI hope you are feeling better soon.\n\nIt does not seem to be a major concern.  Just something to note if you are having urine tests while taking.\n\n- (cited below) While crystalluria has been observed in some intravenous rat studies, urinary crystals are not formed in the bladder, being present only after micturition and are not associated with nephrotoxicity. \n\n- (cited below) It is tempting to associate crystals with a risk of urolithiasis, but the majority of patients with a crystalluria do not have and will not develop kidney stones.\n \nGet better soon :-)

water volume in your cells and thereby your tissues is at a higher than normal level.  so rather than the excess water leaving your body through urine, you are retaining it.  lack of adh can cause this, so can high salt intake etc.

It is a good question and 100% normal. \n\nIt's called Cold-induced diuresis.  As your body cools your blood vessels constrict, this is called vasoconstriction. Vasoconstriction creates greater volume pressure in the blood stream. The kidneys pull off excess fluid to reduce the pressure. A full bladder results in body heat being used to keep urine warm rather than vital organs. Once the person has urinated, it precious body heat will be used to maintain the temperature of vital organs. So in the end urinating will help conserve heat.

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.
