Urine is body waste. It smells bad because it it the toxins which leave your body. It's all the fluid you've drank throughout the day plus a mixture of uric acid and ammonia. It would be surprising if it smelled like aftershave. Incidentally, urine comes from the blood, as gross as that sounds. The kidneys filter waste from the blood and store it in the bladder, as urine, for disposal.
Urine has an odor for several reasons. First, urine contains ammonia. Then, when urine stands for a while, it spoils. Unless the person has an infection, urine is sterile when it first comes out. However, it soon attracts bacteria. Urine contains broken down blood proteins in the form of billirubin, so bacteria may be able to feed on that. In addition, urine may contain blood, pheromones, and/or hormones - each adding their own scents. Female urine may contain some traces of menstrual blood, since the urethra is located above the vagina in women. Male urine may contain androgen hormones which are known for odor, and those hormones are also found in sweat.
Another thing of note is that a number of mammals have scent glands, so urine from dogs and cats may have an additional odor. Cat urine is quite musky and may also contain a higher concentration of ammonia since cats are naturally carnivores. That is how the extra protein they eat breaks down.
Imagine having a glass of orange juice, coca cola, milk, water, and other stuff, then leaving it in the window with the hot (the window being the stomach) sun coming through all day (stomach heat). Would you drink it or even smell it?
What is the function of the urethra prior to birth?
It functions the same before and after birth, to conduct urine from the bladder to outside the body for elimination. Urine is developed in fetuses when the baby swallows amniotic fluids and as fluids are provided via the blood from the mother.
The urine that is released in utero combines with the other wastes and fluids in the amniotic fluid and is critical for maintaining the necessary fluid levels in the amniotic sac so that the fetal lungs will properly develop. If there is an obstruction of the urethra that prevents the urine from flowing into the amniotic fluid, the fluid level in the sac can go too low and the lungs will not properly develop, and the kidneys and urinary system can be severely damaged by the obstruction.

you should drink lots cranberry and fruit juices if that does not work then go and see your gp or doctor you should drink lots cranberry and fruit juices if that does not work then go and see your gp or doctor
What is the function of the sphincter in the urinary system?
The diaphragm is the main muscle involved with the respiratory system. It either contracts or expands to allow air in or out of the lungs, which makes you breathe.

Could peeing with a tampon in be bad for you?
No, a tampon goes into the vagina so it has no effect on your urethra or urination. If a woman uses tampons with strings she should move the string out of the way to avoid the string getting wet, this could increase risk of infection by giving bacteria and yeast a warm moist place to multiply.
How do you effectively cut off your penis?
DON'T! If you want to get circumcised, see a urologist.
This is not something you want to do on your own. I am assuming you wish to make your penis more "aesthetically pleasing" to yourself or partner by circumcision.
Consider the following things before you go ahead with your plans.
Excess bleeding from a botched attempt at circumcision can result in death.
The penis has many blood vessels making it very likely to hemorrhage during the procedure. In addition, it is common for the frenular artery to be unintentionally cut, resulting in excessive bleeding.
Other dangers of circumcision include minor to major infections.
An accidental mutilating deformity of the penis.
Partial amputation of the penis.
Even when done by a qualified medical practitioner, it is Very painful.
Even when done by a qualified medical practitioner, it will be two weeks before even YOU can stand to touch it because of the pain and as for sexual relations....you are going to be celibate for many weeks.
Please seek advise from a doctor before you do this to yourself.
Does the urinary system have two urethras?
What dangers does a fetus face who is born with only one urethra?
What keeps urine from leaking?
The ureter tubes move urine from the kidneys to the bladder using something known as peristalsis. Peristalsis is a rhythmic and smooth contraction of muscle tissue to create a "wave." A good way to think of it is like squeezing tooth paste from a tube. It is due to this contraction of the muscles that pushes urine forward that it does not spill back in to the ureters.
What hormone signals the kidney to make less urine?
That hormone is called ADH or antidiuretic hormone. Diuresis means producing urine and antiduresis is the opposite.
Urine is the body's way of eliminating fluid waste products. Urine contains waste or excess materials and toxic substances. Urine's main content is water. In fact 95 per cent of the urine excreted is water. The other major and common constituents are sodium - 0.4 per cent, ammonia - 0.05 per cent, phosphates - 0.6 per cent, urea - 2 per cent, sulfate - 0.2 per cent and creatine, urobilinogen, casts, in minute quantities. Normally, only water soluble substances are excreted in the urine.
Urine is produced by the kidneys as a process of cleaning the blood and excreting the unwanted soluble waste products from the body. The kidneys filter out the waste products such as toxins, excess water and mineral salts from the bloodstream. They filter, clean and purify about 150-180 liters of blood and recycles it daily. The urine formed in the kidney is drained by ureter into the bladder for storage. The urethra brings out the urine from the bladder, when time and place permit thus you get the "urge" to pee.
What do you do if you don't urinate everyday and you are male?
You wouldn't explode as long as you urinate when you have to. Your question is simply how long should one wait between urination times. Well, that is going to depend on many things, with the most important one being how much fluid intake is going on. 'All else being equal, the more one drinks the more one will produce urine and need to go to the bathroom. In general, urinating about every 2 to 3 hours or 8 times in a day would be normal (if you are awake 24 hours). Waking up to 2 times during the night to urinate is also considered to be within normal limits.' So basically the more you have to drink the more often you urinate. If you do drink a lot, but still no often urination, I advise you to consult a specialist/ Doctor. Khuja_owl Answers.
Kidney infections, the most common being one called pyelonephritis, can lead to death if untreated. Yes, the risk increases in a patient with only one kidney. For this reason, you should see a doctor immediately if you have pain while urinating, notice blood in the urine, or have recently developed flank pain.
These symptoms, especially with regard to the urine, are also indicative of a lower urinary tract infection (UTI), which is the most common cause of pyelonephritis. What happens most frequently is that the bacteria causing the UTI (usually E. coli) climbs its way up the urinary tract and infects the kidney, causing pyelonephriits.
What are the differences between urinary system and reproductive system?
In a woman, they are completely separate, and in a man, they are almost completely separate. The Urinary system starts in the kidneys. The kidneys remove waste from the blood. Water and waste goes from the kidneys into the urinary bladder. From there, with a man, it goes through his prostrate through his penis and out. His reproductive system begins in his testes. They are in his scrotum, which hangs behind his penis. Tubes leads from his testes to his prostate and carries sperm to the prostate. The prostrate gland produces semen, it stores the sperm in the semen in little sacks, and then it will release it through the penis. The male urinary and genital systems only join for a short distance in the urogenital system.
A woman does not have a prostate. The urethra empties just in front of her vagina.
Why is more urine produced on cold days than on hot days?
On a cold day, an individual usually does not drink as much water as they do on a hot day. Also, we do not sweat as much on a cold day as we do on a hot day. This results in a higher concentration of urine on a cold day.
Where does urine exit the body?
The urethra is the name of the tube structure through which urine is excreted from the body.
Try drinking 3 quarts of water per day, and see if you can flush the germs out of the bladder. The best home remedy, though, is to drink lots and lots of cranberry juice. BUT, if the burning is still there after 3 days, or if it becomes very uncomfortable, or if you have a fever over 99 degrees, see a doctor to get anitbiotics. This condition should not be left to get worse!
Which urine condition as detected by urinalysis is an indication of impaired kidney function?
albuminuria
- presence of protein albumin
What are the similarities between the urinary system and the excretory system?
the similarities between human kidneys and the animals kidneys are that they both serve the same purpose, other than the creatures without back bones. they both have the ureta conected, and both have the renial vain connected, there are many other reasons of similarities, if this isn't enogh, try google p.s. : srry about the misspells
What do you call the male urethra?
In case of Male Excretory and Reproductive systems are combined by Nature.In Excretory system, you have two Kidneys, two Ureters,(Not Urethra.)and one urinary bladder for to store urine.From Urinary bladder, you have what is called as Urethra, for passage of urine.All these structures are common to both males and females.In case of females length of Urethra is very short. It makes them difficult to hold urine for longer duration of time.(Simple Physics.)In case of males reproductive system is also attached to Excretory system. Sperms are produced in two Testes. They travel a very long journey. (More than 12 meters.)From Epididymis, you have Vas Differns travelling through inguinal canal and then joining the Urethra, which is surrounded by Prostate Gland. (There are two Seminal Vesicles are attached to Urethra. They provide bulk to Semen,60 %, during ejaculation.)Prostate gland(Which contribute 30 % in Semen.) encloses about 4 to 5 cm of urethra.Then, you have about 1.5 cm of Membranous part of Urethra.(Bulbourethral gland is attached to this part of Urethra.) Then starts Penile Urethra. which is about 15 cm long.( In total about 20 cm long.) So Male Urethra performs two functions. 1)Passage of urine from urinary Bladder.2)Passage of semen during ejaculation.
How does kidney failure affect the urinary system?
The kidneys are the starting point of the urinary system, the organ where urine (waste liquid materials) are filtered out of the blood stream. Dysfunctional or nonfunctional kidneys create abnormal urine, and usually an abnormal amount of abnormal urine. This can range from anuria (no urine) to polyuria (urinating multiple times a day) and from urinating basically straight water (clear, colorless, USG <1.003) to urinating pus, blood, serum, or some combination thereof.
Anything can make someone die,but pee most likely not unless you dont ever go and ur bladder bursys which would take a longtime to happen and u would die from the urge and strain of not going pee,odd question though
How much left in the bladder after empting?
A 1,000 pound horse produces about 31lbs. of manure and 2.4 gallons of urine a day.
Hope this is what you were looking for.
The wall of the urethra usually coapted at rest. Diameter of urethra can be measured during micturation, which is as following;
Prostatic urethra 10-12mm.
Membranous urethra 6-8mm.
Spongy urethra 8-10mm.
Narrowest part of urethra is external urethral meatus, which is a 6mm long vertical slit.
