Learning the Digestive System Chapter 16-17

The Digestive  System tends to have minimum anatomy with more complex physiology to study.   This tends to be a difficult unit of study, but you have many tools which will aide your successful learning. You must choose a system that works and launch into your study each day.  You will find additional help outside your text at the prenhall website,EAP CD(E, D, G)  (NOTE:  You may find it easier to just run the CD from your computer.).  (Click Start, Run, Browse for your CD.  Select Start_EAP3e_CD from the files displayed.), ADAM Interactive Anatomy (LRC Lab). PLEASE NOTE:  The website is NOT for your textbook, but the content is identical (human body is a human body is a ...) so the activities will be the same., ADAM Interactive Anatomy (LRC Lab). You have approximately 1 week to complete this task.  Allow your digestive juices to flow through this learning experience.!

At the end of the study of this system, the successful student will be able to:

• Identify the Histological organization of the 4 major digestive layers and the structures contained in each.   p. 488-490

  • mucosal

  • submucosal

  • muscularis

  • serosa

• Recognize the structure and function of the Accessory organs  p.503-508

  • salivary glands( 3)* Know all 3 by location and function

  • pancreas

  • liver (note the hepatic duct)

  • gallbladder (note the cystic and common bile duct)

• Be able to relate the processing and absorption of Nutrients to nutritional problems  P. 510-512

• My Lecture will cover the calculations listed below

  • Carbohydrate digestion and absorption

  • Protein digestion and absorption

  • Fat digestion and absorption

  • calculate the calorie value of each of the above in grams

  • calculate stored energy per body pound of fat.

  • calculate the recommended Dietary Allowances (RDA's) in food sources

In addition, from the lab studies , the student will be able to

• Recognize using Anatomic models and drawings the following structures p. 177-193

  • oral cavity( tongue and teeth by name, location and function)

The following sources of information will help you master the  the digestive system and the related structures for which you are responsible.

1. Prenhall website:    

   1. The text material has great potential to help you learn the many components of the Digestive system:

      1. Digestive (17)

   2. Review the quizzes

   3. including matching

   4. and most importantly, labeling exercises:

      1. Digestive System.

2. Textbook:  Read the objectives.  Use them as a guide when you 

   1. skim read the chapter to get a feel for the content and how the different topics are related

   2. reread the chapter look for the critical points and preparing for lecture

   3. study the chapter to learn the critical content

   4. review the chapter preparing for the quizzes and exams

3. Lecture:    Attend all lectures.  Use them to 

   1. identify important points

   2. ask questions of points not well understood in the text

   3. measure your learning comprehension

4. Lab:     Attend your scheduled lab and take advantage of open times to continue to study  
               Use your labs to correlate text structures to actual specimens in lab

5. EAP CDrom:  Interact with the materials on your CD
