1. Know the foregut, midgut, and hindgut’s roles in digestion. 2. Know where and how the three macromolecules break down (both chemically and mechanically) in the foregut and midgut and how they are absorbed into the body. 3. Understand the necessity of a strongly acidic stomach and how protein digestion occurs within the stomach. 4. Describe how the stomach creates and maintains an acidic stomach. 5. Describe how the small Intestine works with the pancreas and liver to finish digestion and start/complete absorption. 6. Know that the large intestine retains digesta long enough to absorb water and nutrients before expulsion. 7. Compare and contrast hindgut vs. foregut fermentation strategies. Know where fermentation happens for each and what strategies are employed to maximize energy and nutrient acquisition.
