The maintenance of proper body pH is critical for proper cellular function. The kidney helps to regulate this by secreting varying amounts of hydrogen ions into urine. This is done via a negative feedback mechanism, which means that the process is self-regulating. When acid levels are too high, the kidney secretes more hydrogen ions. When acid levels return to normal, secretion stops. This type of feedback loop is important for maintaining stability and preventing extreme changes in pH levels. Hormones from the kidney, nerve impulses from the brain, and positive feedback mechanisms are not directly involved in regulating pH levels in the kidney.
