The Urinary System
By Robert, Jose, and Quinn.
The Kidneys
 The kidneys make
sure that your blood
has enough vitamins
and minerals.
 Each kidney has
millions of urinemaking units called
nephrons.
The Kidneys cont.

The nephrons clean
your blood in 45
minutes
 Blood passes
through the kidneys
300 times a day
 If both kidneys fail,
people can use a
dialysis machine
The Bladder



The Bladder Holds the
urine made by the
Kidneys
The Bladder is the last
part of the urinary
system
The bottom of the
bladder is called the
urethra, where the
wastes exit the body
The Liver and the skin


There are two other types of
organs: the skin and the liver
The skin sweats out some
wastes
The skin is the largest organ
in the urinary system
because it covers the whole
body
The Liver and skin cont.
The liver, like the kidneys,
Also cleans the blood for
it’s part in the system
The average liver cleans about
1.5 quarts per minute. That
is about 540 gallons a day,
or 13 million gallons a life
time
