Do You Know About Your Kidneys?
The kidneys are a pair of vital organs, each about
the size of a fist, that perform many functions to keep the blood clean and
chemically balanced. They are in the abdomen of the human body and filter the
blood to remove toxins, waste chemicals and water. Every day, a person’s
kidneys process about 200 litres of blood to sift out about 2 litres of waste
products and extra water. This filtered fluid is then concentrated to form urine.
From the kidneys, the urine passes out into the ureters (connecting pipes) to
be stored in the bladder until releasing it through urination.
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
- 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 (wee).
- Our kidneys also 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.
