Most people have two kidneys, organs that sit in the back of your abdomen. Your kidneys’ primary function is to filter your blood. They also remove waste and balance your body’s fluids. Common kidney conditions include kidney disease, kidney infections, kidney cysts and Kidney Cancer.
The main function of the kidney is to eliminate excess bodily fluid, salts and byproducts of metabolism – this makes kidneys key in the regulation of acid-base balance, blood pressure, and many other homeostatic parameters.
