You just sat down to have lunch consisting of a ham sandwich and a glass of water. Using your knowledge of the digestive system (and notes if required), explain the sandwich's pathway when it gets ingested, digested, absorbed, and finally defecated by the body. Starting with the oral cavity and ending with the anus: List all the alimentary canal organs that the food passes through and any accessory organs that assist those organs. You must also list the different sections of an organ if applicable (i.e., sections of the small intestine). Describe what the food is called at each phase of digestion. (i.e., bolus) Indicate all mechanical and chemical digestion processes and enzymes required to break down the sandwich and absorb major and minor nutrients into the bloodstream. Assume that the sandwich contains carbohydrates, lipids, and protein.
