Digestive Anatomy Diagrams

Above is an image of the digestive track of a Norway rat from (Finegan and Stevens, 2008). This image was used to represent the disgestive track of the eastern chipmunk because these species share taxonomic characteristics (both in Order: Rodentia)

Above is an image of the disgestic track of a chicken (Finegan and Stevens, 2008). This image was used to represent the disgestic track of the mallard duck because both are omnivorous birds.
