Over the course of a human life of pissing, how does it not end up like Swiss cheese.
What are the differences in composition of regular used urethane and excessively used urethra.
A plastic straw being the healthiest?
A marshland reed being the average?
A long un inflated balloon that’s as had the air filled and let out 50 times?
Not really, if by meat you mean muscle tissue. It’s made out of epithelium, one of the four major tissue types, along with muscle, connective tissue, and nervous tissue.
I have no idea what the OP means by an “excessively used urethra.” Age can affect the urethra, such as thinning of the lining which can cause urinary incontinence in older women. Urinary problems in men are mainly due to an enlarge prostate blocking the flow.
Living tissue repairs itself to some degree. The urethra generally doesn’t expand so much in the act of urination that the total number of urinations over the course of a lifetime has much effect, compared to the generalized aging of the tissue itself. The inside of the urethra is protected from urine by the secretion of mucus. There is no reason that a urethra should end up “looking like Swiss cheese,” and I’m not sure why the OP should think that.
If the OP has concerns about his own urethra, the best thing to do is to consult a medical professional.
Living things don’t deteriorate like inanimate objects. Aging is an entirely different process for an object like a garden hose than for a living thing’s urinary tract. Living things repair themselves (and actively prevent wear to begin with as well), while nonliving objects weather, erode, rust and become brittle due to extended use or exposure. Comparing urethras to straws and balloons illustrates that you don’t quite understand the difference yet.
As **Colibri **said, the inner surface of the urethra is protected by a layer of mucus. That mucus is continuously renewed. Just like the snot in your nose is continuously renewed. If all is going normally, the urine only touches the mucus, not the “meat” = epithelium underneath.
Kind of like an engine will not wear hardly at all if you keep the oil changed and nothing fails in the lubrication system. As long as there’s enough fresh oil to prevent metal-to-metal contact, there’s almost no wear.
Last of all, the OP is saying heavy pee-ers, e.g. alcoholics, might pee 2 or 3 times as much as normal pee-ers. *Assuming *for a moment that that’s even remotely true …
As long as the system is “designed” with 2-3x the minimum lifetime capacity, it won’t fail before something else does. While alcoholics *might *pee 3x normal, they also don’t tend to live as long as normal folks; they’re wearing out other less robust systems at an even greater rate. So they usually die of something else before they wear out their urethra.
Pee is not caustic. You could pee on your foot ten times a day and it would mostly just get wet.
Now, stale pee degrades into ammonia, which is caustic. So if you’re peeing on your foot ten times a day, be sure to take off your shoes first. Standing around in ammonia-producing shoes would be bad.
The bladder is subject to outside interference, loss of muscle control, interstitial cysts, neurological diseases, yes, excess alcohol intake, that can leads to pain, damage, overactiveness or difficulty voiding.
Unless you are playing too many games with your urethral sex toys (http://www. aliexpress.com/w/wholesale-urethra-sex-toy.html) the urethra is unlikely to suffer damage from proper use. The body is full of tubes. The urethra probably gets the least usage of any over a lifetime.
Fun fact for the day: if you’re trying to place a Foley catheter in a female patient, and you’re having trouble figuring out which one the urethra is, gently stroke a gloved finger or your spare Betadine swab over the area where it ought to be. The urethra will wink at you. The vagina won’t.
If that fails, be sure you have two Foleys. Put one in the hole that you think is the urethra. Got urine? Awesome, you’re done. If you don’t get urine, that was probably the vagina. LEAVE THE FOLEY IN. Now you have (probably) only one other hole as the option. Put the second Foley in that hole. Urine return? Awesome. Take out the first Foley. No urine return? Time to get the ultrasound and check the bladder.
And now you know why the nurse brings in extra Stuff and leaves with some of it unopened sometimes.
But yeah, as long as you’re not sticking things up there for medicine or recreation, the urethra is one of the least problematic organs.
