Digestion
Follow mechanical and chemical digestion through the alimentary canal, then connect villus structure with nutrient absorption.
Your study notes
01 / LESSON
Build the explanation.
- Distinguish ingestion, digestion, absorption, assimilation and egestion.
- Match digestive enzymes with substrates, products and locations.
- Explain how villi absorb sugars, amino acids, fatty acids and glycerol.
02 / NOTES
The essentials, in one place.
- Mechanical digestion increases surface area; chemical digestion hydrolyses molecules.
- Bile emulsifies fats but does not enzymatically digest them.
- Villi combine large area, thin barriers and good transport routes.
- Absorption enters the body; assimilation uses the absorbed material.
03 / ACTIVITY
Test the idea by changing something.
Predict the result first, run the activity, then explain what changed and why.
04 / DIAGRAM
Make the connections visible.
Chewing and the start of starch digestion.
Acid, mixing and protein digestion.
Most chemical digestion and absorption.
Water and ion recovery; faeces formation.
Cover the labels, redraw the sequence or comparison, and explain each connection aloud.
