All of the following are normally found in urine except:
Correct answer: D. Glucose
- A. Sodium ions
- B. Uric acid
- C. Creatinine
- D. Glucose
Explanation
Glucose is not normally found in urine in significant amounts in healthy individuals. Normally, the kidneys filter glucose from the blood and reabsorb it back into the bloodstream. However, if blood glucose levels are consistently high (as in diabetes mellitus), the kidneys may not be able to reabsorb all the glucose, leading to its presence in the urine, a condition known as glucosuria.

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.
