The pH of human urine is
Correct answer: C. 5.00
- A. 7.4
- B. 3.5
- C. 5.00
- D. 8.0
Explanation
The correct answer is 5.00. Human urine typically has a pH range of 4.5 to 8.0, with an average around 6.0. A pH of 5.00 falls within this normal range, indicating slightly acidic urine, which is common due to the excretion of excess acids. Option A (7.4) is incorrect because it is the pH of blood, not urine. Option B (3.5) is too acidic for urine, potentially indicating a health problem. Option D (8.0), while possible, is at the extreme end of the normal range and is not typical for the average urine pH.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
