What is the function of the urethra?
In humans, the urethra carries urine (from the bladder) out of the body, and in males it also carries semen from the testes through the penis (for sexual ejaculation). In both men and women, the urethra is the tube through which urine is excreted from the urinary bladder to outside the body. Urine flows from the bladder out of the body by way of the urethra when the sphincter muscle is relaxed. The urethral sphincter muscle is at the base of the bladder and controls the release of urine from the bladder into the urethra, which then flows out of the meatus (opening at the end of the urethra) when urinating. The urethra is approximately 1 1/2 inches long in females and around 8 inches long in males. The urethral meatus is located at the tip of the penis in men and between the clitoris and vaginal opening in women. In males the urethra also carries semen from the ejaculatory duct outwards through the penis. The semen is directed from the reproductive organs through the vas deferens tube for semen that intersects with the urethra at the prostate gland. A valve there at the base of the urethra directs the flow of either urine or semen through the urethra and out of the meatus. the urethra is the opening where your urine comes out. This is the tube present in both men and women that carries urine from the bladder to the outside world. For obvious reasons it is longer in men than in women, giving men a lower chance of a Urinanry Tract Infection. The function of the Uretha is to transport urine and semen from the male and urine from females out of the body. the urinary systems uretha is the part where that pee comes out.
Is bright yellow urine normal?
It's not necessarily a danger sign. You may be simply offloading a high concentration of vitamin C (which, when you over-consume, simply dumps the excess to the urine), or betacarotene, the precursor to vitamin A, and the coloring agent in lots of orange fruits and veggies such as carrots or cantaloupe. Also, a lot of the B-vitamins can have this exact effect. If the urine is clear, this is a good sign and makes the vitamin density the most likely explanation. It could also mean that you're somewhat dehydrated and you're expelling very rich urine. In that case - rehydrate! :} Note that this works better with liquids that have some electrolytes in them - some salts. These include sports drinks like Gatorade, various juices (such as orange, pineapple or tomato), or simply drinking water and having a banana or two (high in potassium - an electrolyte). Far less common are cases of kidney problems. But if this is a new phenomenon for you, and has no other symptoms, I wouldn't worry unless it persists. I would definitely rather be excreting excess vitamins in my bright yellow (normal) urine, than having clear urine and vitamin-starved body cells. More comments from WikiAnswers contributors: Asparagus is another veggie that will make your urine bright yellow. Drink lots of water (8 glasses a day) and that will help to flush out the kidneys. Bright yellow urine can mean that your body is dehydrated and also it can mean you are highly acidic. Yellow urine indicates that a person is able to flush out acids stored in the body or that a person's body is not able to process the food that he is eating. If it is the first situation it is good. If it is second situation it is bad. Liver does not get any water if taken with meals or shortly afterward. Such water is flushed out of the body faster. One should drink 1 hour before meals to be able to get the water to the liver. Except for this period one should not drink water. Drinking one hours before meals will help water to stay in the body for a longer period and work on the acids and toxins for a longer time. Taking certain vitamins will turn your urine intensely yellow. Urine should be almost clear in color, if you're drinking enough clear fluids. The less you drink, the darker your urine will become, and some medications will affect urine color. If you're not taking meds, then up your water intake; drinking cranberry juice also helps the kidneys to flush any toxins which can lead to urinary tract infections. Water, water and more water! Six 8 oz. glasses a day is what is good for you, but even 4-5 will make a difference. To add, it is usually the B Vitamins, found either in multivitamins or as a additional supplement, that can make urine bright yellow or even orange. Other medications, such as ones for urinary tract infections, can do the same thing (such as phenazopydidine, AZO-standard, etc.). Read the information the pharmacy gives along with any prescription medication you are taking to see if this is a common side effect of them. Otherwise, you can certainly see a physician if you are concerned. Although this is a commonly mentioned "fact" in the news, there is no scientific evidence behind the "8 glasses of water a day" theory. Before you spend a bunch of money on supplements (many of which are useless), try drinking more water. Urine is yellow because the major waste product of the blood, bilirubin converts to urobilin in the kidneys. Urobilins are yellow. Drinking more water will dilute your urine and it will appear clearer. While it is true that many are re-thinking the "8 glasses a day theory," it is also true that not being properly hydrated can cause urine that is bright yellow in color. B Vitamins and other medications can also cause discolored urine. Pay attention to your fluid intake (and remember to drink before you feel thirsty), and you should see a change in color.

What are the tubes called that carry urine away from the kidneys to the urinary bladder?
As I believe has already been stated the Ureters, which are also the source of blockages from kidney stones. Not where they come from that is but where stones large enough usually 5 mm can cause blockages. 2 and 3 even 4 mm stones csn take up to 45 days to pass but usually do. The danger is if stones are present in both Ureters and are causing blockages then the urine can back up and seep into your abdomen and cause infection throughout, this is called sepsis and is life threatening which can kill you in a matter of hours. They usually implant a stint bypassing the Ureter to avoid such an incident, the good news is your body was designed with redundancies. You only need 1/3 of 1 kidney to sustain bodily function.

What happens if you drink urine?
In the short term it can be useful if you are very short of water. In the long term it just puts back the poisons which have been carfeully extracted from your body. Some scientists believe that drinking your urine can make you much healthier than you are... So,drinking your urine can may improve your health and and perhaps help to fight many diseases too...Just remember there is no documented evidence to support any therapeutic benefits from drinking urine at this point. It is almost all water with a few minerals etc that are readily available elsewhere & has no magic ingredient(s). It is sterile though, so if you must drink it to stay alive-you could. Remember that urine is one of the processes by which the body gets rid of waste products. In the particular case, urea from the metabolism of protein, excess salts, and other waste products. In the Far East, drinking of urine is a not a rare practice, but in western eyes it has little to recommend it. Aron Ralston, (127 Hours Beteen a Rock and a Hard Place) whilst canyoning in Utah in 2003, had his arm jammed by a falling rock, and several days later had to self-amputate his lower arm. Out only for a day trip, his water had long gone, and tried to drink his urine. Even in his extremis, he does not recommend the practice. As to what happens, you'll only concentrate the salts and urea you should be trying to get rid of. If your water intake is adequate, you'll do OK, but otherwise, it will not improve your circumstance. You can drink pee provided that you supplement it with water and food. There have been some people that drank urine as a health supplement: Mahatma Gandhi for one. There are some arguments for it being beneficial. However you cannot drink just urine continuously without fatal effects. This is an option with shipwrecked sailors. In 'Mutiny on the Bounty' the death of four sailors is recorded from their choosing this option. Many times seafaring peoples have been lost at sea, afloat without benefit of fresh water (potable fresh water) for the purpose of drinking, only to find that the consumption of saltwater acts as a diuretic, causing one's body to pass more liquid than it takes in. The overload of salt also acts on the brain physiologically to cause irrational thought patterns to surface.
Asked in Urinary System
How does the excretory system remove drugs?
Drugs are metabolised by the liver and are broken down into water soluble products - these can sometimes be highly harmful, which are later removed by kidneys. This process of converting fat-soluble drugs into water soluble metabolites that can be excreted by the kidney is carried out in the liver. The kidney is the most important organ involved in the elimination of drugs and their metabolites. Removal by kidneys is just like removal of other wastes through nephron and glomerular filteration. Possible ways of excretion include: •Breath for gaseous wastes •Urine for most metabolites •Saliva •Perspiration •Faeces •Milk •Bile •Hair

What causes a person not to pee?
Assuming that the person is not simply making a conscious effort to hold their urine, there are many possible reasons for an inability to urinate, many of which should be properly diagnosed by a physician. The bottom line is that if you are certain that minor dehydration is not the issue, GO SEE A DOCTOR. The inability to urinate could indicate and/or cause serious health problems, check it out sooner than later. Here are some possibilities: Dehydration (the body has not received enough water from food and/or drink to produce sufficient urine to trigger the urge to excrete it). Some non-prescription cough suppressing medications (cough syrups, etc.) can make urination very difficult. Some prescription and non-prescription medications may have side-effects such as an inability to, or difficulty with, urination. Prostate problems. Bladder, Urinary tract, Kidney, or other infections. In men, an erection, or with some women, sexual arousal, can also make it difficult, if not impossible to urinate.
Asked in Urinary System, Bladder
What tube carries urine from the bladder to the outside of the body?
The tube is called a urethra. The tube called the urethra allows urine to leave the bladder and exit the body. Both men and women have a urethra. In women, it carries only urine. In men, it can carry semen or urine. The urethra should not be confused with the ureter, which is a tube that delivers urine from the kidneys to the bladder.

What does it mean if urine smells like bleach?
Your urine shouldn't have a really noticeable smell to it. Are you sure it's a bleach smell...possibly an ammonia smell? If so maybe you should drink a whole lot more water to dilute it and if you drink sodas maybe lay off of them for a while. You can get bad bladder infections if your urine is too strong. I know water is not very yummy though! Lol

How do eunuchs pee when they don't have penises?
They would usually put a splint in the urethra to keep it from healing over. They also would give them a lot of wine and that would make them pee all the time so that the hole wouldn't heal over. In addition: according to a book written by a woman whose grandmother lived in a harem, after the hole finally healed, eunuchs carried a small thin straw in their turbans which they would insert for urination. Many young boys died in the process of making eunuchs. A sword would be heated red hot and the genitalia would be cut off with it. The area would be cauterized by the sword, of course. Then after a splint was inserted, the wound would be covered with animal dung in an attempt to heal it. Throughout history, of course there have been other methods, all painful in the extreme. Except as part of transgender surgery (which restructures the urinary flow), simple castration does not involve the penis, but only the testicles. Even these may not be removed in the process, merely rendered incapable of providing sperm or continuing the production of male hormones.

Small traces of protein in urine?
From my experience, traces of protein in the urine can be considered normal. If you have concerns with protein in the urine, a dipstick urinalysis can be easily performed in the comforts of your own home. Test your urine each time you go to the restroom. If you have a trace of protein on 2 or more occasions in the same day, it make be worth asking your doctor about. Normal urine contains some protein, but when the protein level consistantly becomes above trace amounts, there could be an underlying kidney problem that should be addressed. Protein in urine can also be the result of excercise, emotional stress, cold or heat exposure, or fever.

What could cause a fatty lump on the back of the neck of a 13-year-old of average weight?
Search webMD and read about cushings syndrome. One symptom of the syndrome is a "buffalo hump". http://my.webmd.com/hw/health_guide_atoz/hw71659.asp A harmless fatty tumor caused a lipoma Some small cysts are called subaceous cysts and can usually be removed in Dr. office with freezing before hand.You should check with Dr. just to make sure. Inhaled steroids for the treatment of asthma can cause a fatty lump. The body tends to use fatty/lipid based substances to neutralize acidity in the body. Fatty tumors in a particular area indicate a high degree of acidity and inflammation in that area of the body. Acidity accumulates from an acidic diet and lifestyle (i.e. stress, pharmaceutical drugs, etc.), a congested lymph system, and under-functioning elimination channels where the acids are normally flushed out of the body (e.g. kidneys). Alkalizing the diet and cleansing the body with a high percentage of fresh fruits and vegetables, increasing hydration to flush out acids/toxins, activating the lymph system with regular movement/exercise, and rebuilding the elimination channels with herbs will address the underlying causes of the body forming fatty tumors.
What if you have four ureters?
Ordinarily you have two ureters, one for each kidney. However, you can have four uretres. It is a congenital abnormality, but it can happen statistically once every 160 person. If you do have such abnormality, you have to check if you have frequent infections, fever, etc. Your uretres could not be connected to your bladder, thus this infection. The infection could be treated with antibiotics. Sometimes you could also undergo a surgery to connect your uretres to the bladder correctly.
