collecting duct
The urine shows a characteristic odor that is caused by the presence of urea. The higher the concentration, the stronger is its smell. In most cases, a bad smelly urine indicates a insufficient diluted urine. In general, it appears as a dark yellow urine.
During reabsoption most of the water exits the nephron and enters the interstitial fluid. This increases the concentration of ions such as potassium in the nephron. In the collecting duct (at the very end) very little water is left and the concentration of potassium, sodium, etc ions rises (including urea). This is why urine is acidic.
It tries really really hard! Nah, i think it depends on how much fluids you have in your system, if your urine is yellow then it has a higher urea concentration. If its clear, a lower urea concentration
The urine of a dog, like the urine of most mammals, is a dull yellow color ranging in intensity from a light lemonade color to a darky murky mango fruit yellow. The difference in colors is due to concentration of the dissolved wastes, particularly urea - lighter colors have a lower urea concentration while darker colors have a higher urea concentration. If you notice anything white or blood-red in the urine, or if the urine color shifts outside the spectrum of basically yellow, you should take your dog to a veterinarian for an examination as these color changes can be a sign of intoxication, bladder infection or cancer.
The kidneys are the organs that directly regulate the concentration of water in the blood by filtering excess water and solutes from the blood to form urine. They also help maintain proper balance of electrolytes in the body by reabsorbing or excreting them as needed.
Most of the responsibility for urine formation lies with the nephron in the kidney. The nephron filters blood, reabsorbs essential substances, and excretes waste products to produce urine. However, other structures such as the collecting ducts and renal pelvis also play important roles in the final formation and concentration of urine.
Wait a month or so, and most of the alkaloids will be undetectable in your system. If you are concerned about a drug test, drink a lot of fruit juice so that your urine is not dilute, but does have the alkaloids diluted.
Please see the link below, which should answer the question as far as Auschwitz is concerned. Most of the larger concentration camps, such as Buchenwald and Dachau, also had crematoria, but they were smaller.
No. The metabolites that are measured are not flushed out by the urine in sufficient quantities for "water doping" to work. In most drug test programs they also run urine concentration tests to see if you have been trying to dilute. That will usually fail you all by itself.
two kidneys, two ureters, bladder, urethra
Yes urine can contain both minerals and vitamins. Certain vitamins taken in excess would be excreted through the urine. Certain minerals can be found in urine as well such as sodium, potassium, chloride, magnesium, and calcium.
Urine gets its normal yellow color from a pigment called urochrome, which is a product of the breakdown of hemoglobin from old red blood cells. The concentration of urochrome in urine can vary depending on hydration levels and diet.
