The small intestine of the pig has significantly more surface area (through folds and villi) than that of the frog, and if you were to remove them, the small intestine of the pig is several times longer than that of the frog. This additional surface area maximizes nutrient absorption by the pig. Why might the pig need more energy from its food than the frog?

Discuss hypotheses for why Burmese pythons deconstruct theirdigestive systems between meals. Similarly, discuss hypotheses forwhy small birds and mammals, having lengthened their intestinesduring cold seasons, permit their intestines to shorten during warmseasons. In other words, why might natural selection favor plastic,rather than static, gastrointestinal morphology?
Describe the mechanisms of digestion and absorption ofcarbohydrates, proteins, and fats in vertebrates, and explain theimportance of enzymes in some of these processes.
Compare how the anterior portion of the alimentary canal (from the mouth to the end of the stomach) of the crayfish and the pig carry out mechanical and chemical digestion

Explain in your own words: What are the unique anatomical structures observed in birds to carry out thefunctions of digestion? Elaborate on these unique structures and provide reasons for theappearance of these unique structures.
Why is the incisors of rodents (such as mice and rats) are larger than humans?
Based on your study of the frog and the pig, how are the digestive systems amphibians and mammals different? List any structural differences, variations in size or location of the digestive and/or accessory organs.

Figure 16.7 Which of the following statements about the digestive system is false? a. Chyme is a mixture of food and digestive juices that is produced in the stomach. b. Food enters the large intestine before the small intestine. c. In the small intestine, chyme mixes with bile, which emulsifies fats. d. The stomach is separated from the small intestine by the pyloric sphincter.
