A lot of time was spent in accurately modeling the human abdomin. Each model wraps around each other and should fit perfectly in a skeleton, depending on it's shape.
I created this for a medical research company, going in and out of the stomach. The stomach texture is not the final product but is usable and the UVs are saved for you. Camera paths are included in the file so you can animate going into the stomach through the large intestine or the mouth. The outer mouth was not finished and is usable, teeth and rough inner mouth included as a bonus.
Also particularly usefull; I kept the large and small intestine stacked so you can change it's shape using one of the lines (hidden in file).
Camera paths included as well.

Included are;
Lighting and cameras
render set-up for Mental Ray
fog set-up
material library I created and a few bump maps needed
stomach and inner stomach
esophagus
teeth
spleen
large intestine
small intestine
liver
kidneys
pancreas
gall bladder
(stomach fluid is not included)

*Included are all the files above in a zipped folder
*You may not minupulate then resale this model, thank you.
