REVIEW SHEET 38 Anatomy of the Digestive System Name: Lab Time/Date: General Histological Plan of the Alimentary Canal 1. The general anatomical features of the alimentary canal are listed below. Fill in the table to complete the information. - Wall layer - Subdivisions of the layer - Major functions Organs of the Alimentary Canal 2. The tubelike digestive system canal that extends from the mouth to the anus is known as the canal or the tract. 3. How is the muscularis externa of the stomach modified? How does this modification relate to the function of the stomach? 4. What transition in epithelial type exists at the esophagus-stomach junction? How do the epithelia of these two organs relate to their specific functions? 5. Differentiate the colon from the large intestine.
