The digestive system ingests food, breaks it down so nutrients can be absorbed, and eliminates what cannot be digested. In the animal kingdom there are a variety of food-capturing methods along with variations in the digestive process. In this comparative anatomy lesson, students will be comparing three predators: the squid, the dog shark, and the cat. Students will compare and contrast their methods of capture and digestion. Students will handle and manipulate digestive organs. In addition, students will walk through the systems in larger-than-life specimens.
