The Virtual Stomach

November 1, 2002 | Source: New York Times

Penn State researchers have devised a virtual stomach, a computer simulation of the gastric motions, stresses and particle breakdown as the belly contracts, based on fluid mechanics.

The simulation may one day help researchers improve the composition of tablets that break down slowly over many hours before proceeding to the small intestine, where drugs are taken up. It may also help understand why nutrients are sometimes released too rapidly or too slowly from the stomach.
