Digestive System Objectives

Digestive Overview

List and describe the basic digestive functions, including the role and locations of both mechanical and chemical digestion; identify the locations of organs within the thoracic (chest), abdominal, and pelvic cavities, and summarize the path food takes from ingestion through processing to egestion as fecal material. 

Upper G.I.T.

Describe the basic functions of the salivary glands, esophagus, and zones of the stomach; provide detail on types of teeth and general tooth anatomy, including enamel, cementum, dentin, and pulp; and explain the significance of digestive chemicals like amylase, pepsin, and hydrochloric acid. 

Lower G.I.T.

List the functions of the small intestine, large intestine, and rectum; describe the structure of the villi of the small intestine, and compare the tissue structures of the esophagus, stomach, small intestine, and large intestine; and explain how lipids are digested, including the organs and chemicals involved.

Digestion Misconceptions

Describe what a misconception is and how a misconception can form; provide examples of digestive misconceptions and explain why they are incorrect; and explain how analysis of stool (fecal material) can provide information about the digestive process. 

Digestive System Quiz

Quiz Directions

Complete all four sections and take the quiz on Canvas.

Use the learning objectives above to guide your studying.

Digestive System Media

Introduced in Digestive Overview section of this guide:

In this media piece you are going back to the three body data parameters you have chosen to study over this course and selecting one that can be qualitatively studied, and one that can be quantitatively studied.

You can study the same body parameter both qualitatively and quantitatively. For example, you could monitor sleep patterns to develop a list of variables that are impacting your sleep (qualitative) and test one of those variables by altering it and measuring whether or not you get more sleep (quantitative).

Qualitative examples: identifying the things that make your heart rate increase (or decrease), identifying factors that make it easier to concentrate while studying, or listing things that cause undesired stress (stress can be positive too, more on that in Module/week 7).

Quantitative examples: keeping track of how many times you touch your face, counting how many steps you take on different surfaces, or measuring how much you can safely lift after working out over time.

You are turning in:

An example of a qualitative approach you can take to studying one of your body data parameters, including how you will generate variables.
An example of a quantitative approach you can take to studying one of your body data parameters, including how you will test one of your variables.

You do not need to carry out both of these forms of data collection for the final analysis, this assignment is to think about different ways data can be collected.

As always, use caution when trying out a new behavior or workout routine.

Media Directions

To be completed after taking the quiz on Canvas.

Upload your quantitative/qualitative media piece to Canvas. If the file is really large, it may help to host it on a webpage and submit the web link to reduce upload time.

Human Biology Portfolio

Portfolio Directions

Keep collecting your body data. Consider adding your qualitative/quantitative media piece to your portfolio so you can check off one piece of evidence of course outcome mastery.
