Analogy
Digestive system is like a living system solving a small survival problem: each part has a job, and the answer depends on how those jobs connect.
Why now: An analogy helps when the definition feels abstract.
Do this: Match each part of the analogy to the science idea.
Learn it
The digestive system breaks large insoluble molecules into small soluble molecules.
Enzymes are biological catalysts with specific active sites.
Bile neutralises stomach acid and emulsifies fats.
