What is the function of kidneys?

Indeed, sir, the kidneys play a vital role in maintaining overall health. Their primary function is to filter blood, removing waste products and excess fluids to form urine. This process helps regulate blood pressure, balance electrolytes, and maintain the correct levels of acids and bases in the body. In doing so, they contribute significantly to a person's general well-being. One might say, the kidneys are like quiet sentinels working tirelessly behind the scenes, essential yet often overlooked.
