A) silicates
B) minerals
C) calcium carbonate
D) calcium oxalate
Correct Answer: D
Solution :
During urine formation, salts and other wastes are dissolved in the filtrate and pass with it out of the kidney as urine. But sometimes, however, certain salts (such as calcium oxalate) do not stay dissolved but instead form crystals called calcium stones. These can partially block the flow of the urine from the kidney.You need to login to perform this action.
