Morphology and Histochemistry of the Liver of Carnivorous Fish Hemisorubim platyrhynchos
The aim of this study was to characterize the normal structure of the liver of Hemisorubim platyrhynchos, a carnivorous freshwater catfish found in Neotropical region, using gross anatomy, histology and histochemistry. Anatomically, the liver presents C-shaped and only two lobes: smaller right and b...
