A Comparison Between the Macroscopic Anatomy of the Cecum in Laboratory Rat and Guinea Pig

Controlled food and maintenance conditions cause both functional and anatomical adaptations of digestive system. The rat and guinea pig, used both as experimental models and as pets, shared common controlled environmental conditions. The two species were exposed during the generation to artificial conditions rather that natural ones. The effects of these conditions on the macroscopic anatomy of the cecum have been documented.
