Step by step
Solved in 2 steps
- Compare and contrast the structure and function of the digestive systems in bony fish, amphibians, and mammals.Why is the digestive system of these animals called incomplete?Does the type of diet of the insect affect the structure of organs/parts of the digestive system? Cite at least four structures and explain such adaptation. Make sure that each division of the digestive system should be represented. Elaborate.
- 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.Enumerate the accessory organs of the digestive system of a cat and give their corresponding functions for food digestion.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 how vertebrate digestive systems are specialized for different diets?Compare and explain the structures of an insect digestive tract specialized forsolid food type with one modified for a liquid diet.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.
