We have two kidneys that have red-dark
color, form of beans grain and measure about
12 cm in an adult person. They are situated
in the posterior part of abdomne one of
each side of the column, where they are
protected by the last finish ribs.
The function of the kidneys is to filter
the blood, removing the produced toxic trashes
in fabrics of the body and also salts and
other substances that are present in excessive
amounts. The water excess in the body and
also the salt are eliminated by the kidneys
in urine way. It is kept thus, the adequate
rocking of liquids in the organism preventing
itself of the swell.
The kidneys also produce responsible hormones
which the control the arterial pressure
and the production and realeasing of red
globule by ossea marrow, the one that prevents
the annemia.
The Blood arrives at the kidneys through
the renals arteries that, in the inward
of the kidneys, divide in lesser vases each
time until they form fine vases that constitute
the glomerulos. In each kidney millions
of glomerulos exist are the true filters
of blood. When the blood passes through
these small vases, the excess liquids and
its salts are eliminated and the urine formation
begins, after crossing some tubes and suffering
many hashings, it will be eliminated for
a common tube, the ureter and then to the
bladder and uretra.
Approximately two a thousand liters of
blood pass for the kidneys every day, being
produced to the end 1.2 liters of urine
per day .If our kidneys have its preserved
function, the more liquid we take, the more
urine will be produced.
