3Video: How does a cow eat?
Cows are ruminants, animals with a unique digestive system that allows them to live on otherwise unpalatable foods by repeatedly regurgitating and rechewing them as "cud." The cud is then swallowed again and further digested by specialized bacterial, protozoal and fungal microbes that live in the rumen, one of the four compartments of a cow's stomach. Learn more about a cow's digestive system in this video segment from Nature.

4Build a Digestive System: Bison
This is an interactive webpage. You can build both the human's digestive system as well as the bison's digestive system. Pay attention to how the two systems are similar and different. You will be comparing them later. The digestive systems of humans and bison are adapted to their diet. Can you reassemble in the proper order the different components of their systems? To each its own digestive system! Humans are omnivores. We have a one-chambered stomach that allows us to extract a high level of nutrients from a wide variety of foods. Bison are herbivores and ruminants. Their four-chambered stomach (helped by cellulose-digesting bacteria) allows them to efficiently extract the energy from the vegetable matter that is their diet.
