  1. Kidney

  2. The kidneys are paired organs, which have the production of urine as their primary function. Kidneys are seen in many types of animals, including vertebrates and some invertebrates. They are part of the urinary system, but have several secondary functions concerned with homeostatic functions. These include the regulation of electrolytes, acid-base balance, and blood pressure. In producing urine, the kidneys excrete wastes such as urea and ammonium; the kidneys also are responsible for the reabsorption of glucose and amino acids. Finally, the kidneys are important in the production of hormones including vitamin D, renin and erythropoietin.

  3. What do your kidneys do? • Your kidneys intervene in numerous processes and balances of the body and control many vital body functions and are amazing master chemists of the body.  The major role of the kidneys is to remove waste from the blood and eliminate it in the urine.  To remove this waste and extra water, blood enters the kidney through the renal artery; blood is then cleaned in the kidney as it passes through tiny filters called nephrons.  One kidney contains about one million nephrons.  Each nephron contains a filtering apparatus called a glomerulus. We have about a million hairpin-like glomeruli at birth, but lose about 100,000 of these every decade of life.  Droplets of filtered blood pass through a number of tubules (tiny tubes) into the medulla, a central collecting region.  The glomeruli and tubules together make up nephrons, long and extremely fine tubes which, if connected, would run for 80 kilometres (50 miles).  The nephrons are the basic working units of the kidneys, controlling the formation of urine. Cleaned blood returns to the body by the renal vein. Waste and extra water removed by the kidney passes through a tube called the ureter to the bladder where it is stored as urine or wee.  When the bladder is full, the urine passes out of the body through another tube called the urethra.

  4. Classic signs and symptoms • • Increased tiredness• Fluid retention – often seen as swollen feet and ankles• Difficulty breathing at rest• Loss of appetite• Nausea• VomitingIt is important to note that signs and symptoms do not appear until serious damage has occurred.
