Overview: “Anatomy of the Digestive System” is part of a larger site entitled “A/P Lab – A Website for Human Anatomy and Physiology” developed by University of Wisconsin - La Crosse for Anatomy and Physiology courses. The site was “developed to enable students enrolled in Human Anatomy and Physiology I & II … to study laboratory materials for practical exams.” The site is a collection of images of anatomical models of the digestive system. The six annotated models of the digestive tract include: 1) Median section of the head and neck, 2) Stomach model (external view), 3) Stomach model (internal view), 4) Digestive organs model, 5) Small and large intestine model, and 6) Liver and gall bladder model. Each model is a picture with labels identifying the different parts or regions of the model.
Learning Goals: After completing this presentation, the learner will be able to:
  • Identify the parts of the gastrointestinal tract
  • Diagram the components of the gastrointestinal system
  • Describe the major gross features of the abdominal organs
Target Student Population: The target student population includes high school and college undergraduate students.
Prerequisite Knowledge or Skills: Students will better understand the materials with some basic understanding of digestive tract anatomy.
Type of Material: This material is a collection of annotated anatomical models of the digestive system.
Recommended Uses: This site can be used for review and practice in identifying the digestive organs. It could be used as a lab practical to view, study, and identify the digestive organs. The site also contains images of the digestive organs that could be used in lectures or on worksheets.
Technical Requirements: The material can be viewed using a web browser such as Mozilla Firefox 19.0+, Internet Explorer 9.0+, and Google Chrome.

Evaluation and Observation

Content Quality

Rating: 4 stars
Strengths:
  • Models are anatomically correct and the labels are accurate
  • Models show the anatomical relationships of each organ to other organs
  • Images are high quality, clear, and well-labeled
  • Site is concise and relevant
  • Content is related to core curriculum within the discipline
Concerns:
  • Does not provide good explanations nor does the site demonstrate / summarize the concept
  • Some general text about each organ might be helpful
  • Review test questions would be useful

Potential Effectiveness as a Teaching Tool

Rating: 4 stars
Strengths:
  • Models are organized well and build upon one another; for example, the digestive tract of the head and neck is listed first, followed by the stomach, and then other organs as you work inferiorly
  • Site provides general foundational anatomical knowledge that all students taking anatomy should know after completing the course
  • Provides a great review for lab practicals
  • Easy to incorporate into a lecture or lab class
  • Simple and clearly labeled images
Concerns:
  • Site is not interactive
  • Site does not ask questions about the structures or provide any feedback
  • It would be nice if the labels could be turned on or off for practice purposes
  • Site does not promote critical thinking or analysis of the anatomical structures
  • No learning objectives listed
  • Site lacks instructions, overviews, and summaries
  • There are no additional resources provided

Ease of Use for Both Students and Faculty

Rating: 4 stars
Strengths:
  • Easy to use and good quality graphics
  • Table of contents is clearly organized and easy to navigate through
  • Images are visually appealing
Concerns:
  • There are no instuctions provided on using the site, although it is intuitive
  • Materials are not engaging or interactive
