Understandings:
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.
6.1.U3: Enzymes digest most macromolecules in food into monomers in the small intestine.
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.
Applications:
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.
Skills:
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.
Nature of Science:
6.1.NOS: Use models as representations of the real world-dialysis tubing can be used to model absorption in the intestine.
