<s>[INST] What do the kidneys do and why are they so important? [/INST] Kidneys are the unsung heroes of your body. They have a very important job of filtering waste and excess fluid out of your blood to make urine.  They also control your blood pressure, help red blood cell production, keep your body’s acid/base balance right and help bone health. Source: DR RICHARD BAER.
