Menschliches Verdauungssystem 3D-Modell

A 3d collection model of Digestive System. Integrated parts. Consist of the following: Esophagus Stomach Small Intestines Large Instestines Liver Gallblader Pancreas Complete with color map and bump maps. This model is ready for 3d medical animation/presentation. This model is consist of different model conversions such as 3ds, max, maya, lightwave etc. This conversions can be open in any latest or old 3d software package. Medical Description: Digestive systems take many forms. There is a fundamental distinction between internal and external digestion. External digestion was the first to evolve, and most fungi still rely on it. In this process, enzymes are secreted into the environment surrounding the organism, where they break down an organic material, and some of the products diffuse back to the organism. Later, animals evolved by rolling into a tube and acquiring internal digestion, which is more efficient because more of the breakdown products can be captured, and the chemical environment can be more efficiently controlled.
