This
is your
"urinary" system. It is
where your urine
(which everybody
calls
"pee") comes from.
When you drink
something, the water
in the drink goes to the
kidneys.
The kidney takes the
water and adds
yellow waste stuff
from your body to
make urine.
The urine then
travels down little
tubes called ureters
to your
"bladder".
It stays in your
bladder until you
pee it out (through
the
"urethra").
When your bladder
fills up you feel
like you have to
pee. After you
pee your bladder is
empty.
You already know how to hold your urine when you are awake. You wet the bed because your body hasn't learned how to hold it when you are asleep. You can teach yourself to hold your urine when you are asleep, by thinking real hard when you are just going to sleep about not letting your urine go. Also, make sure that you pee just before you go to bed, so you start the night with an empty bladder tank. An alarm helps you to learn what it feels like when you pee in your sleep, by waking you just when you start to wet. After using the alarm for several nights your body learns to not let your urine go or you learn to wake up and go to the toilet.
