Urea and Water.
The normal glucose concentration in urine ranges from 0 to 15 mg/dL. The glucose concentration in urine becomes zero when no glucose has spilled over into the 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.
Urea is a byproduct of urine. All animals produce urea in their urine, not just cows.
Healthy urine consists of 95 % water,ammonia , potassium, hydrogen, sodium, uric acid and urea and bilirubin,
As air temperature rises humans sweat more. This means we lose water - which would otherwise have been released as urine. There is thus a higher proportion of urea compared with water in the urine; so, rises in temperature increase the concentration of urine.
kidney filters and maintain a normal concentration in cells toxics are wasted out as urine
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.
Urea is one of the substances in urine, and urine is in your blood stream until the kidney extract the urine from your blood.
