The Liver video examines the morphology of the liver, blood flow, lymph, and bile; the relationship of blood flow to pathology; and cellular morphology and function.

The Gallbladder video covers the gross structure of the gallbladder and its ducts, bile secretion and recycling (enterohepatic circulation), and the microscopic structure and function of the gallbladder.


The Tubular Organs video is an overview of the layers and structures that make up tubular organs within animals.


The Oral Cavity video examines the structure and function of the lips, cheek, tongue (mechanical and gustatory papillae), developing and maturing teeth, and palate.


The Tooth Development video discusses the development of the brachydont tooth, histology of the developing tooth/mature tooth, and compares the hypsodont tooth.


The Esophagus video discusses the structure and function of the esophagus by examining multiple specimens and comparing differences amongst the domestic species. Includes discussion and examination of avian esophagus and crop.
