High level of _ and _ in the blood and the contributing factors in the formation of kidney stones.
Correct answer: A. Calcium, oxalate
- A. Calcium, oxalate
- B. Calcium, magnesium
- C. Calcium, sodium
- D. Sodium, sulphate
Explanation
Kidney stones are principally formed by calcium as the cation, and one of its most common forms are calcium oxalate stones which have oxalate as the anion. Hence, the correct option is A. In option B, Magnesium does not contribute to kidney stones. In option C, sodium does not contribute to kidney stones. In option D, both sodium and sulphate do not contribute to kidney stones.

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.
