Must know

1Trace food digestion and nutrient absorption.
2Understand the core idea of Digestive System.
3When revising Digestive System, recall the definition, one correct example, and the mistake students most often make in...
4Nutrition supplies food, digestion breaks complex food into soluble nutrients, and circulation transports nutrients and...

Formula / process

1Trace food digestion and nutrient absorption.
2For Digestive System, remember the definition, one example, and one common mistake before starting practice.
3Digestion breaks food down; absorption moves digested nutrients into blood.
4Nutrition supplies food, digestion breaks complex food into soluble nutrients, and circulation transports nutrients and...

Exam traps

1Students may say digestion and absorption are the same.
2Digestion breaks food down; absorption moves digested nutrients into blood.
3Did you name both processes separately?
4Students may confuse breathing with respiration.

Answer frame

Start with the exact keyword or formula before adding explanation.
Use one example, diagram cue, observation, or substitution to support the answer.
For 3 marks: definition, reason, and one supporting point.
For 5 marks: setup, method/process, example, conclusion, and final check.
