2. Today we will Define digestion List and describe the parts and functions of digestive organs Demonstrate the pathway food takes in the digestive tract.

3. What is digestion? The process of breaking down food material into various nutrient forms to be absorbed into the animal’s body.

4. Three Types of Digestive Systems 1. Ruminant 2. Hindgut Fermenter 3. Nonruminant (Monogastric)

5. Ruminant An animal with 4 distinct compartments in its stomach ◦ Rumen, Reticulum, Omasum, Abomasum Swallows its food essentially without chewing ◦ Regurgitates it, chews it thoroughly & re- swallows it.

6. Hindgut Fermenters Simple stomach animals with massive large intestines, colon, and cecum Uses fermentation to break down foods like ruminants, but digestion occurs in the “hind gut”…large intestines.

7. Nonruminant (Monogastric) Simple stomachs Food passes from the mouth to the stomach through the esophagus ◦ Digested in a single stomach compartment with the help of digestive juices

8. Major Parts of the Monogastric Digestive System Mouth- teeth and tongue Esophagus Stomach Small intestine Large intestine Rectum
