Changes

Your kidneys are bean-shaped organs, each about the size of your fist. They are located near the middle of your back, just below the rib cage. The kidneys are sophisticated reprocessing machines. Every day, your kidneys process about 200 quarts of [[blood]] to sift out about 2 quarts of waste products and extra water. The waste and extra water become [[urine]], which flows to your [[bladder]] through tubes called [[ureter]]s.  [http://kidney.niddk.nih.gov/kudiseases/pubs/yourkidneys/]
