How is urine formed in our
body?
Our urinary system consists mainly of two bean shaped glandular
organs in the lumbar region of the abdominal cavity, which are called kidneys.
They are reddish brown in color. Each kidney is approximately 11 centimeters
long, 5 centimeters wide and 2.5 centimeters thick. Each of them weighs about
150 grams. Do you know what the function of the kidney is?
Human Kidney
The main function of the kidney is to purify our blood by
removing the impurities from it. They work as filters. The kidneys also
maintain proper proportion of every constituent in the blood. If sometimes the level
of sugar salt or water in blood excesses the normal level, the kidneys excrete
the excess amount from it. They also regulate the formation of urine according
to the exigencies of the situation and thus do not allow the blood to become
extra thick or thin. The undesirable acids and bases of the blood come out of
the body as urine.
Each kidney has millions of coiled capillaries. Blood
enters the kidneys through the renal artery and passes through these
capillaries and the dissolved impurities are filtered our. The purified blood returns
to the lungs. About 200 liters of blood pass through the kidneys every day. The
impurities removed from the blood pass form the kidneys to a bag where they are
stored for some time. This bag is known as the bladder. When the bladder is
sufficiently filled, one feels the urge to empty it. We pass urine primarily to
empty this bladder. Normally, an ordinary person passes 1.5 liters of urine in
one day.
Any disorder or damage to the kidneys is very dangerous
for the body. If the kidneys become defective, impurities in blood go on
increasing and have poisonous effect on the body. If somebody’s kidneys stop
faction, the person dies within a few days. It is, therefore, absolutely
essential to have proper treatment of any defect or disease of the kidneys. It
is necessary to take proper quantity of food in order to keep them healthy.
Excessive eating compels the kidneys to work more to expel more excretory
material and thus the chances of any damage to the kidneys increase. To keep
the kidneys healthy, we should take eight to ten glasses of water every day.
