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.]
