The kidneys are organs of the
excretory system.
>S(11),156,153

The kidneys remove waste from the blood,
and excrete waste from the body as
urine.

Once the kidneys remove the wastes,
the urinary duct carries them to the
urinary bladder.
>E(11),156,155
*155,20
From there, the urine passes to the
cloaca and out the cloacal opening.

Both human and frog have two kidneys
and filter wastes in a similar way.

Wastes leave the blood and flow into
the excretory system in the kidneys.

Humans reabsorb most of the water that
enters their kidneys. Frogs also
reabsorb water.
>E(01),0,159

But frogs that live in water, reabsorb
less. They pass lots of water in their
urine.
