The normal range of urinary output per day in human adults is-A. 50 mlB. 10 mlC. 400- 2000 mlD. 200 ml

The correct answer is C. 400-2000 ml.
1. Normal Urinary Output in Humans:
o The normal range for urinary output in human adults typically varies between 400 milliliters (ml) to 2000 milliliters (ml) per day. This can fluctuate based on factors like hydration levels, diet, physical activity, and health conditions.
2. Factors Influencing Urinary Output:
o Hydration: If the body is well-hydrated, urinary output tends to be on the higher end of the range (closer to 2000 ml), while dehydration can result in lower output.
o Kidney Function: Healthy kidneys are capable of filtering and excreting waste products in the form of urine within this range. Certain conditions, like kidney disease or excessive fluid intake, can affect urine volume.
o Diet: The consumption of salt, caffeine, or diuretic substances can also influence urine production.
3. Why Other Options Are Incorrect:
o A. 50 ml: A daily output of only 50 ml is abnormally low and may indicate a medical issue like dehydration or kidney failure.
o B. 10 ml: This is extremely low and would likely point to serious kidney or urinary tract issues, such as anuria (complete absence of urine production).
o D. 200 ml: While this could be a plausible output in certain conditions, it is generally lower than the expected daily range for an average adult.
The normal daily urinary output for human adults typically falls between 400 ml to 2000 ml, making C. 400-2000 ml the correct answer.
