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.
Is it ok for a boy to go pee with another boy?
Not if he's 14, but when they are 10 and under, sure. When I was a boy I urinated into the toilet at the same time as my brother. Hence the whole expression about [urine] sword fights that are common today to talk about. Just make sure they don't hold each others penises or do any fondling. That would be grounds for a penalty, not to mention possible gay behavior.
Can sperm and urine be expelled from the urethra at the same time?
No they don't, the paths are like a valve, one closes when the other is in use
There is no process in the body that would cause urine to be greasy. If ut seems that urine is greasy then look for something outside the body, such as Vaseline or ointments used in that area.
What does it mean when you pee in your sleep?
Hmmm, it might be the fact of your body releaseing the uirne(Resason for wetting the bed)As for doing it on someone? I would possibly say that it's eathier you hate this person your urineating on, or that your subconius perhaps like the idea of peeing on someone as an erotic type fantasy.
What is the distension of the ureter known as?
The most common reason or term for a distended uterus is pregnancy. Though there are other reasons for a distended uterus like leiomyomas which are also known as uterine fibroids, any symptoms should be checked out by a physician.
the substance might you expect to is dead blood cells
What glands does the urethra pass through?
The urethra passes through the prostate and the penis in the male.
What are some of the substances filtered from the blood by the kidney?
substances that are excreted from the kidneys are urea, uric acid, creatinine, toxins, drugs, plasma inorganic ions,(Na+,K+,Ca2+..ect.) H+, HCO3-, of course H2O, and anything else the body doesn't need that's found in the blood plasma.
substances that are reabsorbed are amino acids, proteins, glucose, water, plasma inorganic ions and anything the body needs that is found in the blood plasma.
the nephrons are nonselective and secrete everything in the plasma, and the capillaries then reabsorb the vitamins minerals nutrients ect. that the body needs back into the blood, everything the body doesnt need goes to the bladder. What will cause the kidneys to lose more water from the blood? Diuretic hormones
If you pee a little in your pants out will you feel a little better?
yes because then you feel control over your body. be careful not to let to much out
How does the urinary system remove wastes from the body?
The urinary system filters waste from the blood and produces urine in the kidneys; then it removes the urine from the body. Adults produce about a quart and a half of urine every day, but that amount can vary greatly depending on how much fluid and what types of foods are consumed and how much fluid is lost by sweating or breathing.
Two bean-shaped organs called the kidneys are found in the abdomen, near the back and just below the ribs. The kidneys are responsible for filtering the blood. The filtrate, as it moves through the kidney tubules, is modified to produce urine. The two kidneys lie behind the peritoneum on the posterior abdominal wall near the 12th thoracic and first three lumbar vertebrae. The right kidney is slightly lower than the left kidney. Each kidney and suprarenal gland is encased in a perinephric fat capsule, which is covered by a membranous renal fascia. Paranephric fat lies outside of the renal fascia.
Each kidney is shaped like a kidney bean (surprised) with an anterior and posterior surface. The renal hilum is located at the medial border and allows the renal artery to enter the kidney and the renal vein to leave. It also allows the ureter to exit the kidney. The internal part of the kidney includes a section called the medulla surrounded by a covering called the cortex. The medulla contains minor calyces that merge to form major calyces. The innermost renal pelvis is formed by the merger of the major calyces.
The body needs a way to store the urine until you have a convenient time to urinate (remove urine from the body). Urine leaves the kidneys and travels down the ureters to the bladder is a thin-walled, bag-like organ that can hold up to two cups of urine.
The bladder is connected to the urethra, which is a tube that opens externally through an opening called the external meatus.Sphincter muscles keep urine from leaving the bladder until the person is ready to urinate. The female urethra is quite short, whereas the male urethra is longer and runs through the penis.
Sometimes in the process of filtering blood and forming urine, salt-and-mineral crystals form in the kidneys. These kidney stones can travel down the ureters and into the bladder. The stones vary in size, and in some cases passing kidney stones can be extremely painful. The stones can become lodged in the ureter, blocking the flow of urine and causing a back-up of urine in the kidney. Treatments include medications and the use of lithotripsy (shock waves) to reduce the size of the stone so that it is more easily passed.
Is there any cure for overactive bladder?
Hypo tonic nurogenic urinary bladder can only be managed than can be cured. Intermittent self catheterisation, surgical removal bladder out let obstruction if implemented early when there are bladder contractions sufficient enough to void normally can revive the bladder . However a hypo-tonic bladder having very weak contractions on urodynamics and fail to revive even one year after ISC is unlikely to be revived though theoretically there is always some hope.
This is quite unfortunate that no sufficient and sustained research has been undertaken so far and this condition is highly discouraged by urology experts and nurses .Electrical simulation of sacral nerves is an option, but with limited success. there is no adequate data on the acceptability and success rate of this procedure. This is not available in many developing countries and very few urologists have expertise in this area.
So to say hypo tonic urinary bladder primarily is nurogenic is one of the most unfortunate diseases esp for men. Regular catheterisation have complications like infections, urethral changes including strictures, false passage, epidydimitis , orchitis, rapid development of resistant bacteria due to the need for repeated use of antibiotics.
Unconventional medicine like homeopathy/ayrurveda unani / acupuncture claim that they can treat this condition but supporting clinical evidence e is pathetically lacking.
This conditions restricts the moments, social contacts, travel and one should have toilet map while working out side. Catheterising in unhygenic surroundings is a real problum., Because of the nature of management this disease can trigger frequent dipressive moods.Fortunately Intermittent catheterisation is available as the only option in evacuating the bladder despite its complications and drugs are more or less empirical.Data relating to Research into drugs that can effectively contract bladder is very limited

Does the urethra convey urine and menstrual flow?
No. The female urethra is just for urine. Menstrual flow comes from the vagina, which specifically refers to the hole underneath the urethra. The vagina is the same opening that a woman uses for sex and gives birth through.
Does the ureter expands as a renal pyramid inside the kidney?
Renal pyramids are the cone shaped tissues in the kidney. The base of each pyramid starts at the corticomedullary border.
How does Tubular re-absorption and tubular secretion differ?
secretion adds material to the filtrate; reabsorption removes materials from the filtrate
Why are women more likely to contract urinary tract infections?
because we have larger holes and it's easier for things to get inside them, also, its closer to our anus. we are just prone for failure
50% of pee is water and the other 50% is just toxins removed from your body!
Some people actually drink their urine, but it contains salts and will dehydrate you if you drink too much. It is usually at least as salty as seawater.
Assuming you are female, It sounds like you have started your period (this happens whether your a virgin or not). This is completely natural and you should not be worried. Talk to your parent/guardian (mother would be best) at the next available opportunity. It is nothing to be ashamed of it is just a sign you are growing up.
NOTE: If you are concerned and know that this is not the signs of a period seek proffessional medical help immediately.
Why is glucose in the urine a sign that something is wrong in the body?
It is bad to have a high amount of glucose in your urine because you will be diagnosed with diabetes. A slightly raised glucose reading can also indicate pregnancy.
Predict what would happen to urine volume if you did not add ADH to the collecting duct?
urine volume would hugely increase ... because the ADH is an anti-urination material.
Will I urinate better after prostrate removal?
If your prostate is enlarged, it is constricting your urethra and impairing the flow of urine. Removal of your prostate would release the constriction and improve the flow of urine. There are other effects of removing the prostate,and there may be other treatments available. Your physician should explain them all to you, as well as the other effects.
