Abstract: A rag-type doll is provided with a hollow body cavity accessible by means of a zipper-closed opening located in the front of the doll. A simulated rib cage is located in the upper portion of the body cavity and simulated, stuffed replicas of the major body organs are located within the cavity. The various organs are located in their approximately correct position within the body cavity and secured to the body cavity and/or each other by means of snap fasteners or the like. The organs are completely removable from the body cavity for instructional purposes. A small bone is also removably located in a pocket in one arm for instructional purposes.
