- From the moment you start to eat an apple, different organs in the body work together to complete the process of digestion. What is the advantage of having multiple organs in the process of digestion? A. The process is more energy-efficient, and organs can perform more than one function simultaneously B. Different systems can compensate for another if the responsible system fails C. Different organs act independently as a transportation system until digestion is complete D. Each organ has a specific function and is specialized to allow the body to supply the correct nutrientsA. What is/are the primary role(s) of the large intestine? a. to complete enzymatic digestion and store indigestible material b. to initiate enzymatic digestion of carbohydrates and to store water c. to absorb water from digested material, with essentially no digestive role of its own d. to secrete water into the material that is left over after all available nutrients have been absorbed e. to digest fats A.

- 1. Go to this figure shown below in your textbook. Examine each of the layers that make up the wall of the gut. You can think of these as concentric tubes, shown below. Label each of these layers, and indicate what type(s) of tissue or specialized cell(s) are contained in each. If a layer is subdivided into even more layers, add this to your label. If there are nerve plexi or specialized structures within or between layers, indicate this also. Aside from the mouth, name one other region of the gut does not fit this particular scheme? How does it differ? (CCCO Copyright © McGraw-H Education. Permission required for reproductioWhich of the following statements is true?a. Intracellular digestion commonly occurs in vertebrates.b.
