Module 7: Digestive System

Introduction: The function of the digestive system is to break down the foods you eat, release their nutrients, and absorb those nutrients into the body. Although the small intestine is the workhorse of the system, where the majority of digestion occurs, and where most of the released nutrients are absorbed into the blood or lymph, each of the digestive system organs makes a vital contribution to this process.

 In this module, you will be studying the structure of the organs of the digestive system via models, diagrams, histology images, and preserved specimens. You will also review the physiological roles of each structure in accomplishing ingestion, mechanical digestion, chemical digestion, hormone secretion, nutrient absorption, and waste excretion.

Upon completion of this module, you will be able to:

1. Describe overall function of the digestive system. (CLO 3)
2. Explain the functions of the individual organs and structures of the digestive system. (CLOs 1-4)
3. Identify the structures of the digestive system and associated parts on a model, in a picture or diagram, or in a specimen. (CLOs 2-3)
4. Identify the histologic structures of the of the digestive system in a microscope slide. (CLOs 2-3)
5. Identify the digestive enzymes involved in the digestion of proteins, fats and carbohydrates, and their site of origin. ((CLOs 2-4)

To achieve these objectives: 

1. Read the Module 7 Introduction 
2. Read Lab 7 in lab manual.
3. Take the Module 7 pre-lab quiz.
4. Complete the Module 7  lab exercises.
5. Take the Module 7 post-lab quiz.
