Welcome! You have come to the right place for further exploring the topic of the Human System: The Digestive System. For most part, our students (including teachers) take digestive system for granted and/or do not understand its implication in our daily lives. It my intent as an educator, to reach as many first-year-teachers as possible, and give them a FREE access to my collection of comprehensive resources. This chapter has been strategically organized into four (4) different lessons to give students a deeper understanding of the digestive system with a heavy focus on the following:
- Diet and Nutrition
- Function of the digestive system
- Structure of the digestive system
- Disorders and Homeostasis
Why is it important to learn about the digestive system? Even, I wonder....
- In nutshell, converting the blueberry muffin you had for breakfast into fuel for your morning swim is the job of your body’s digestive system. Like finely tuned plumbing, the tubes and organs of the digestive system route food through the body, in the process breaking down nutrients into smaller particles that can be passed through the walls of the intestines into the bloodstream and carried throughout the body for use in metabolism. This system then flushes out material not needed for energy or cellular growth.
- Therefore, in order to understand the intricacies of how the digestive system is able to do such miraculous things so efficiently and effectively without you knowing, you will have to go on a journey, a journey that is inexpensive and filled with a lot of fun: Cool labs/experiments and entertaining activities/games etc.
- Food Facts:
b) swallowed food moves into the pharynx (throat) at 20-25 feet per second, enough to move the food deep into the esophagus;
c) the average meal takes between 15 hours and two days to pass through the entire alimentary canal.
