TITULO: ......................................................

There are two kidneys in the body, and they are situated on either side of the vertebral column, between the thick muscles of the back and abdomen. Each kidney is approximately 10 cm long, 6 cm wide and 4 cm thick. Each one weighs about 140 gm.

      The major function of the kidneys is to remove waste products from the body by producing urine. They contain about one million microscopic units called nephrons. Their function is to receive and filter all the blood in the body once every twelve minutes. They remove waste material from the blood and return useful substances to the circulation. In this way they enable blood pressure to remain constant.

       The process of filtering the blood is as follow: first of all, blood  enters the kidney from the renal artery and flows into the glomeruli: small knots of capillaries which act as a filter. Fluid then passes into Browman’s capsule, but the filter does not allow blood cells and large protein molecules to enter the capsule. As the filtered fluid passes on, 80% of the water and sodium salts in it are removed returned to the blood. The remaining liquid passes into collecting ducts, where water is again removed. The concentrated urine enters the renal pelvis, passes into the ureter and finally enters the bladder.
