The kidneys play a crucial role in maintaining the balance of electrolytes, including phosphate. In renal failure, the kidneys' ability to excrete phosphate is impaired, leading to altered phosphorus levels. This is because the kidneys regulate phosphate excretion to maintain a balance with serum calcium, a process that is disrupted in renal failure.
