Abstract
Abstract A model for the demonstration of the human organ system, including organs of the digestive system. The model includes a foldable support surface having the shape of a human silhouette. An abdominal tray is attached to the mid-section of the support surface and a first group of elements representative of human organs is housed within the abdominal tray. In an adult embodiment of the model, the first group of elements includes elements representing a human liver, pancreas, gall bladder and associated ducts. A second group of elements is partially housed within the abdominal tray and is removable. The second group, as provided in the adult embodiment of the model, includes elements representing a human esophagus, stomach, greater omentum, small intestine, mesentery, appendix, large intestine and rectum. Both the first and second groups of elements are substantially comprised of a flexible material such as a color-coded calico, cotton cloth. Ducts may be comprised of color-coded chenille stems. The greater omentum and mesentery may be preferably comprised of color-coded nylon netting. A color-coded outline of the stomach, small intestine, large intestine, esophagus and rectum is attached to the abdominal tray so as to provide points of reference for reattachment of the second group of elements.
