The digestive system is a complex process that involves the breakdown and absorption of nutrients from the food we eat. It's a vital system that sustains life, and yet, it's often taken for granted. In this POGIL investigation, we'll explore the different components of the digestive system, their functions, and how they work together to keep us alive.
If the question asks why a structure looks a certain way, the answer is almost always related to increasing surface area for better efficiency. Final Thoughts
The teeth grinding food or the stomach churning (peristalsis).
If you are working through a worksheet, keep these tips in mind:
Instead of asking "What does the liver do?", a POGIL might ask, "Based on Model 2, what would happen to fat digestion if the bile duct were blocked?" This requires application, not just recall.
| Molecule | Starts As | Digestion Begins | Digestion Finished | Absorbed By | | :--- | :--- | :--- | :--- | :--- | | | Starch | Mouth (Saliva) | Small Intestine | Capillaries (Blood) | | Protein | Polypeptide | Stomach (Pepsin) | Small Intestine | Capillaries (Blood) | | Fat (Lipid) | Triglyceride | Small Intestine | Small Intestine | Lacteals (Lymph) |
Since "POGIL" refers to a specific teaching methodology (Process Oriented Guided Inquiry Learning), a review of a Digestive System POGIL typically focuses on student interaction with model data rather than just memorizing facts.
