1) Why does the inside of the stomach look like a brain?
The folds in the
stomach are called
rugae. They allow the
stomach to expand
greatly. When you eat a
lot, the rugae will slowly
smooth out as they
accommodate the
growing stomach.

Yahoo answer = 50/50 very bad
Wikipedia = better, still not 100% perfect (it is written by
normal people, not scientists or researchers)
If you want to find VERY good sources of information,
try scrolling down in your searches and looking for
universities or medical research. Sometimes you can
spot them by seeing a ".edu" These will almost always
be correct. Example.... "function of bile".....

Our Bodies?
There are 2 types of toxins:
1) Exogenous Toxins - chemicals that are made
OUTSIDE your body, and then you ingest them.
2) Endogenous Toxins - harmful chemicals that are
made INSIDE your body.
So, you can eat, drink or inhale toxins. ALSO, your
healthy body makes toxins naturally!
Many of your healthy organs produce byproducts that
are harmful (toxic) to your body! Your excretory system
gets these toxins OUT of your body!

A few examples....
1) Processed foods!
2) Pollution (traffic, factories)
