CLEANING THE BLOOD
The primary job of the kidneys is to clean blood. They filter and remove waste and excess fluid from thousands of pints of blood daily. They are responsbile for ensuring the body remains healthy by retaining its chemical balance. If both kidneys are working properly, the body has 100% renal function.
SYNTHESIS OF RED BLOOD CELLS
One of the lesser-known functions of the kidney is the role it plays in the sythesis of red blood cells. The kidney produces a hormone called erythropoietin, this promotes the formation of red blood cells in the bone marrow.
There are certain cells within the kidnes that are responsible for this job and they are sensitive to sudden changes in oxygen levels in the blood. When they detect that oxygen levels within the kidneys are low, they release erythropoietins, which, in turn stimulate the bone marow to form more red blood cells. The ability of the blood to carry more oxygen is, thus, increased.
