Based on how digestion is compartmentalized along the mammalian alimentary canal, what digestive functions would you expect these parasites to have?Would you predict chitin to be digestible by humans? Explain why or why not.How does the digestive system of a nematode or annelid differ from that of a flatworm? In what ways is the digestive system of an annelid worm more efficient than that a flatworm?
- What would happen to the feeding pattern of fruit flies (coming from a food which has maltose and starch) when they live together in a fruit which contain maltose ?Some animals, such as rabbits, whose digestive systems include hindgut fermentation, re-ingest the products of digestion. What function do you think this serves?What are the structures of an insect digestive tract that are specialized for solid food type? What structure is the one modified for a liquid diet? Compare and explain.
- Human vegetarians, unlike true herbivores , have no highly specialized fermentation chamber , Explain How is this reflected in the structure of digestive system of a human and a deerwhy are Ruminants able to thrive even if they do not get all the essential nutrients in their diets, while mono-gastric animals are not so fortunate and will show signs of malnutrition if these nutrients are not in their feed?Food digestion occurs in much the same way in all vertebrates and many invertebrates. Which describes this common process?
- Provide two characteristics of the digestive tract for an animal that eats mainly termitesMany digestive enzymes are synthesized in the pancreas and released into the duodenum. Why do mammalian digestive systems go to the trouble of producing pepsin in the stomach? What does pepsin do that others do not?Does the type of the diet of the insect affect the structure of organs/parts of the digestive system? Cite at least four structures representing each division of the digestive system and explain such adaptation.
