Changes that Occur in the Mucosal Lining Along the Alimentary Canal

Investigation of the Changes that Occur in the Mucosal Lining Along the Alimentary Canal Course Goal (Student Learning Outcome):  By the end of the course the student will be able to explain and discuss the changes that occur in the lining of the alimentary canal from the mouth to the anus via Powerpoint presentation. Purpose:  The student will use Internet micrographs – microscope-generated photographs of prepared slides of tissue samples from various areas of the alimentary canal, e.g. mouth, esophagus, stomach, duodenum, jejunum, ileum, colon, anus – to prepare a powerpoint presentation illustrating the functions of the various digestive organs, focusing on the changes in the mucosal lining of the organs. Assessment:  Student will be assessed using a rubric which models the institutional competencies. Research the changes that occur in the wall of the alimentary canal from one location to the next, focusing on the mouth, esophagus, stomach, duodenum, jejunum, ileum, colon, and anus.  Four legitimate sources must be used, one of which can be the textbook.  For each area, describe the layers of the walls and relate it to the function of that location. Use the micrographs from the internet to observe prepared slides of tissue from the wall of the mouth, esophagus, stomach, duodenum, jejunum, ileum, colon, and anus. Create a Powerpoint presentation containing  8-10 slides.  Include Internet micrographs and descriptions of each.  In the text, focus on the histological changes that occur throughout the alimentary canal and how the histology of each area is related to the function of that area. Refer to the attached rubric to insure that you have fulfilled all research, communication, presentation, and application requirements.
