What do your kidneys do? Healthy kidneys act like a filter to make sure the right amount of wastes and fluids are removed, they keep the proper balance of salts and acids in the body, and produce hormones. Each day your kidneys process around 200 litres of blood, with around 1 to 2 litres of waste leaving the body as urine. Our kidneys make three important hormones, erythropoietin, renin and active vitamin D. Erythropoietin stimulates the production of red blood cells, renin is involved in the control of blood pressure and active vitamin D controls calcium uptake and helps make strong bones.
Your kidneys intervene in many processes and balances in the body and control many vital body functions. Your kidneys are 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. The nephrons are the basic working units of the kidneys, controlling the formation of urine. One kidney contains about one million nephrons and 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). 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. The process of removing waste and extra water in simple terms is:
- Food and drink enters the stomach and are broken down into nutrients
- Solid waste products are removed and nutrients enter the bloodstream.
- Nutrients are used by the body for energy, growth, repair and maintenance of body functions.
- This process creates waste which is removed by the kidneys.
- Extra nutrients not immediately needed by the body are also removed by the kidneys.
- Waste products and extra water move from the kidneys to the bladder, then leave the body as urine

Why does ureter obstruction kill a cat?
If the cat's ureter is obstructed, there is no place for the urine generated by the kidneys to go. As the pressure on the kidneys and bladder increases, one of two things could happen: some part of the system could rupture, causing internal bleeding, or the kidneys could fail, causing the cat to be poisoned by his own waste products.
