                  1. Villi
                    1. Increase the surface area of epithelium over which absorption is carried out
                      1. Villi absorb monomers formed by digestion as well as mineral ions and vitamin
                        1. Different methods of membrane transport are required to absorb different nutrients
                      2. Annotate a diagram of the digestive system
                        1. Micrograph in transverse sections of the small intestine
                          1. Tissue layers
                            1. Muscles
