Lift the left lobe of a frog's liver
and you'll see a raisin-sized green
sac.
>S(11),226,221
*221,22
This is the frog's gall bladder.
Bile made by the liver is stored here.
>S(11),226,222
*222,22
Since bile is used for breaking down
fats, the gall bladder is part of the
digestive system.
>S(11),226,223
*223,22
When needed, bile flows to the small
intestine.

>E(11),226,224

The cystic duct carries bile from
liver to gall bladder.
>E(11),226,225
*225,22
The gall bladder condenses the bile,
which then flows out through the bile
duct.
>E(10),226,0

Human gall bladders and frog gall
bladders have a similar structure.
>S(01),0,227
*227,32
And both are connected to the liver by
the same kind of duct.

Frog and human bile are both made out
of the waste products of red blood
cells.
>E(01),0,229

Thus, making bile serves a cleansing as
well as a digestive function.
