Animals of several species have been used from the origins of the civilization for the scientific development, but among all of the experimental models to the which peptic ulcers can be induced, the rats Wistar, doubtless, is the used. The objective of this work was to accomplish an anatomical and histological description of the stomach of rats Wistar seeking to increase knowledge on it is species, and allowing larger access to the scientific community that he/she makes use of the species in peptic ulcer model.
