Maintaining Water BalanceEdit
The Kidneys And Urinary SystemEdit
The kidneys in mammals are bean-shaped organs that lie in the abdominal cavity attached to the dorsal wall on either side of the spine (see diagram 12.2). An artery from the dorsal aorta called the renal artery supplies blood to them and the renal vein drains them.

Kidney Tubules Or NephronsEdit
Diagram 12.5 - Several kidney tubules or nephrons

Diabetes And The KidneyEdit
Other Functions Of The KidneyEdit
Normal urine consists of water (95%), urea, salts (mostly sodium chloride) and pigments (mostly from bile) that give it its characteristic colour.

- http://health.howstuffworks.com/adam-200032.htm How Stuff Works. This animation traces the full process of urine formation and reabsorption in the kidneys, its path down the ureter to the bladder, and its excretion via the urethra. Needs Shockwave.
