Which of the following substances is/are NOT reabsorbed by the kidneys?

Correct option is B

·        Creatinine is not reabsorbed by the kidneys in significant amounts. 

·        Creatinine is a waste product that the body releases through urine. It is a breakdown product of creatine phosphate, which comes from muscle and protein metabolism. 

·        In contrast, water, glucose, amino acids, and salts are usually reabsorbed by the kidneys. The amount of each substance that is reabsorbed depends on the body's needs. 

·        The kidneys play a vital role in filtering blood and removing waste products from the body.
