kidneys maintain your body's fluid balance. (so if you've not been drinking much they produce concentrated urine, if you've been drinking loads they will produce dilute urine to get rid of the excess fluid) they also help you excrete toxic waste products from your body- such as urea which is a breakdown product from the protein we eat. they also produce erythropoetin which is the hormone that tells us to make more red blood cells.
