kidneys in medicine

The kidneys are vital organs that filter blood to remove waste products and excess fluids, forming urine. They help maintain the body's balance of electrolytes, regulate blood pressure, and produce hormones that support blood cell production and bone health. Located on either side of the spine, each kidney contains tiny filtering units called nephrons. Proper kidney function is essential for overall health, and issues can lead to conditions like chronic kidney disease or failure. Maintaining hydration, controlling blood pressure, and avoiding excessive salt and toxin intake support healthy kidney function.
