6.1 - Digestion and absorption
Assessment statements
| DCS Topic Code | Statement | Guidance |
| 6.1.U1 | The contraction of circular and longitudinal muscle of the small intestine mixes the food with enzymes and moves it along the gut. | |
| 6.1.U2 | The pancreas secretes enzymes into the lumen of the small intestine. | Students should know that amylase, lipase and an endopeptidase are secreted by the pancreas. The name trypsin and the method used to activate it are not required. |
| 6.1.U3 | Enzymes digest most macromolecules in food into monomers in the small intestine. | Students should know that starch, glycogen, lipids and nucleic acids are digested into monomers and that cellulose remains undigested. |
| 6.1.U4 | Villi increase the surface area of epithelium over which absorption is carried out. | |
| 6.1.U5 | Villi absorb monomers formed by digestion as well as mineral ions and vitamins. | |
| 6.1.U6 | Different methods of membrane transport are required to absorb different nutrients. | |
| 6.1.A1 | Processes occurring in the small intestine that result in the digestion of starch and transport of the products of digestion to the liver. | |
| 6.1.A2 | Use of dialysis tubing to model absorption of digested food in the intestine. | |
| 6.1.S1 | Production of an annotated diagram of the digestive system. | |
| 6.1.S2 | Identification of tissue layers in transverse sections of the small intestine viewed with a microscope or in a micrograph. | Tissue layers should include longitudinal and circular muscles, mucosa and epithelium. |
