6.1 Digestion
Do you remember how to draw the digestive system? Work in pairs:
 * Starter**
 * One draws
 * One labels
 * Neither can speak
 * Your work will be graded by another pair

Q - Apart from the assessment statement what did this task teach you?


 * Assessment statements** (IBO notes added to some points to clearly indicate what needs to be understood and what does not)
 * 6.1.1 || Explain why digestion of large food molecules is essential. ||
 * 6.1.2 || Explain the need for enzymes in digestion. The need for increasing the rate of digestion at body temperature should be emphasized. ||
 * 6.1.3 || State the source, substrate, products and optimum pH conditions for one amylase, one protease and one lipase. Any human enzymes can be selected. Details of structure or mechanisms of action are not required. ||
 * 6.1.4 || Draw and label a diagram of the digestive system. The diagram should show the mouth, esophagus, stomach, small intestine, large intestine, anus, liver, pancreas and gall bladder. The diagram should clearly show the interconnections between these structures. ||
 * 6.1.5 || Outline the function of the stomach, small intestine and large intestine. ||
 * 6.1.6 || Distinguish between absorption and assimilation. ||
 * 6.1.7 || Explain how the structure of the villus is related to its role in absorption and transport of the products of digestion. ||
