What percentage of urine is typically composed of water?

  1. 80%

  2. 90%

  3. 95%

  4. 100%

The correct answer is: 95%

Urine is essentially a liquid waste product filtered from the blood and is primarily composed of water, with the typical percentage being around 95%. This high water content is crucial as it allows for the proper excretion of waste products, electrolytes, and other substances dissolved in the urine. The remaining 5% consists of urea, creatinine, uric acid, and various ions and molecules. Understanding the composition of urine is important in clinical settings, as variations in concentration can indicate hydration status, kidney function, and other health-related issues. The correct answer reflects the typical makeup of urine, emphasizing the significance of water in this biological fluid.
