Plastic bone, Dissected fetal pig, and Photograph of a bone would be the best models to illustrate the formation of blood cells. Computer-generated models may be helpful to visualize the process, but they do not accurately represent the actual biological structures and processes involved in blood cell formation. The plastic bone, dissected fetal pig, and photograph of a bone, on the other hand, provide a more realistic representation of bone and the bone marrow, where blood cells are produced. These models can provide a clearer understanding of the location and process of blood cell formation.
