Explore the digestive systems of monogastric animals (horses, pigs, and chickens) and ruminants (cattle, sheep, goats, and deer). Watch as a professor of animal science uses models, computer-generated graphics, laparoscopic images taken within the system of a live animal, and digestive tracts removed from slaughtered animals to teach about prehension, mastication, simple digestion, and ruminating. Viewers explore the entire digestive system of a pig, chicken, and steer to identify organs and to understand the tissue structures and functions. The instructor dissects organs to expose contents and secretions that aid digestion. Review questions are presented at the end of each section, the video concludes with 10 identification and multiple-choice questions. 35 minutes. Copyright 2000.
