True
Why is the fatty tissue surrounding the kidney important?
it stabilizes the position of the kidneys by holding them in their normal position
Can girls urinate while standing?
I'm sure there are a few but it's rare. More comfortable and no "accidents" sitting down.
I have seen women in Africa wearing long skirts suddenly stop, stand for a while with their feet about two feet apart and carry on, leaving a puddle behind. No wet spot on the skirt either.
Yep, that's how you can do if you wear a skirt and no underwear. But over here most women do which is why we squat.
How do you urinate without a sound?
If you are male, aim for the inner walls of the urinal or toilet - urinating on the sides will decrease splashing and noise.
If you are female, you might try putting some toilet paper into the water before you sit down, so that you are not urinating directly into the middle of the water.
What is the best prevention against kidney stones?
A simple and most important lifestyle change to prevent stones is to drink more liquids-water is best. If you tend to form stones, you should try to drink enough liquids throughout the day to produce at least 2 quarts of urine in every 24-hour period.
People who form calcium stones used to be told to avoid dairy products and other foods with high calcium content. But recent studies have shown that foods high in calcium, including dairy products, may help prevent calcium stones. Taking calcium in pill form, however, may increase the risk of developing stones.
You may be told to avoid food with added vitamin D and certain types of antacids that have a calcium base. If you have very acidic urine, you may need to eat less meat, fish, and poultry. These foods increase the amount of acid in the urine.
To prevent cystine stones, you should drink enough water each day to dilute the concentration of cystine that escapes into the urine, which may be difficult. More than a gallon of water may be needed every 24 hours, and a third of that must be drunk during the night.

Do the kidneys share one ureter?
No, each kidney has its own ureter leading to the bladder so there are two ureters.
Does anyone else pee when they laugh?
Yes. Urination while laughing is quite common and called "stress urinary incontinence". While laughing the stress placed on the muscles in the urethra are relaxed, leading to a small flow of urine after laughing.
What takes urine directly to the urinary bladder?
Ureters take urine directly to the urinary bladder. The urethra takes urine out of the body. Urine is liquid that has been filtered through the kidneys.
Two glands that sperm pass on their way from the testicles to the urethra?
Sperm pass the prostate and the seminal vesicle, on the way from the testicles to the urethra.
How would hypertonic urine be produced from an isotonic blood plasma?
# Water is reabsorbed all along the nephron. # Urine becomes hypertonic (salty) because of the loop of Henle and the collecting duct. # Loop of Henle # The descending limb of the loop of Henle can't absorb salt, and the ascending limb can't absorb water. # Salt passively diffuses out of the lower portion of the ascending limb. # The upper part of ascending limb actively transports salt into tissue of the renal medulla. # Increase in salt in the direction of the inner medulla. # Urea leaks from the lower portion of collecting duct and contributes to a high solute (salt) concentration. # Water leaves descending limb of the loop of Henle, returning to the blood. # Urine is hypertonic to blood.
What is electrolyte balance refer to?
Having the proper balence of Sodium(Na+), Potassium(K+), Calcium(Ca2+), Magnesium(Mg2+), Chloride(Cl−), Hydrogen_phosphate(HPO42−), and Hydrogen_carbonate(HCO3−) in your body. This can be obtained by the proper nutrient intake, for example fruits such as bananas,oranges, etc.
"Cysto" means related to the urinary tract; "-scopy" means to look in/at for diagnosis or treatment. A cystoscopy is a test procedure in which a flexible tube with a camera on the end is inserted up the urethra (tube that carries urine to the outside) into the bladder.
About one hour prior to the test, a nurse administers a light sedative or muscle relaxer. An IV is started, if one is not already running. Then the patient is wheeled into the X-Ray department. There, the patient is given fast acting sedation (count backwards from 100 and you're asleep before you get to 98). The tube/camera is inserted through the first sphincter; the urologist checks its patency (how well the sphincter opens and closes). The urethra walls are inspected, then it passes through the bladder sphincter. Exam is done of the bladder walls. If required, tools can be inserted through the tube to biopsy the bladder tissue. X-Rays can be taken as well.
The procedure lasts between 30-60 minutes. A catheter is in place when the patient awakens. It is removed within 24 hours.
*Note: The first urination can be quite painful because of bladder spasms.
What is pathway for sperm from testis to urethra?
Semineferous tubules, straight tubules, rete testes, efferent ducts, ductus deferens (vas deferens), ejaculatory duct, prostatis urethra, membranous urethra, spongy urethra, external urethral orifice.
Testes (Testis) -> Epididymis -> Vas Deferens -> Urethra.
What is the Pigment that gives urine its normal yellow color?
Urine contains breakdown of bile pigments, such as urobilin (urochrome), and stercobilin, which are yellow.
see:

The yellow colour comes from the pigment bilirubin which is a product of red blood cell break down.
It depends on why it is sore. Is it from intercourse, or, does it have an actual sore there? If it is an actual sore, see your doctor. If it is from Intercourse, then, probably just a little irritated, but, if doesn't get better within a few days, see your doctor.

What happens when kindeys don't work?
The 2 kidneys filter the blood & create urine, which is passed on to the Bladder, so the body can get rid of waste & toxins. When they fail, the blood doesn't get cleaned & the system becomes toxic & your other organs fail and you die.
