Which of the following is NOT a function of the kidney?

The kidney’s role centers on managing body fluids and waste: it regulates water and electrolyte balance (osmoregulation), filters blood to remove metabolic wastes and forms urine, and helps maintain the acid-base balance of the body. It does these by filtering blood, reabsorbing what the body needs, and secreting additional wastes into the urine. Filtration of bile, however, is not a kidney function. Bile is produced by the liver, stored in the gallbladder, and released into the digestive tract to aid fat digestion. It isn’t something the kidneys filter into urine. So the statement about filtering bile does not fit with what the kidneys do.
