According to the Dolphin Rescue Center,due to the fact that dolphins share the characteristic of a three chamber stomach with a cow, this gives more evidence of the dolphins evolution from a terrestrial ancestor. The DRC also mentions that the majority of the breaking down of the food takes place in the fore stomach(F). Most of the digestion occurs in the main stomach(M). And in the pyloric stomach (P) the rest of the digestion occurs, and empties the contents into the intestinal region. Dr. Michael J. Farabee discussed in his article, Animal Cells and Tissues, the stomachs of mammals contains four major tissues. These include smooth muscle tissue, loose connective tissue,nervous tissue, and epithelium tissue.
