A large portion of the stomach is removed during a sleeve gastrectomy. This video provides a 3D animation of how the procedure is performed and what the gastrointestinal system looks like afterwards.

This animation shows an artist's rendition of the immune system function in the gastrointestinal during Crohn's disease. It also shows a possible future treatment for the disease.

This stylized animation shows what a cell might look like at very high magnification. It begins by showing the cell membrane and the proteins that hold the cell together. The video continues to describe the internal workings of a cell. While the narration is very detailed and accurate, this video may use terminology that is advanced for a general audience.

An upper GI endoscopy is a procedure in which a thin tube is placed in the mouth and throat and advanced to the stomach and first part of the small intestine. As the animations shows, the endoscope contains a tiny video camera and often small surgical instruments which can be used for diagnosis or treatment.
