Below, you will see a concept map of the digestive system. Boxes represent either a division/classification or an organ of the digestive system. Please complete the concept map by filling in the missing information. THE DIGESTIVE SYSTEM For each box that you fill in, provide 1-2 sentences (brief!) on its anatomical orientation and features. Question #2 On your concept map, highlight the organs involved in each of the four functions of the digestive system in the following colors: • Ingestion - YELLOW • Digestion - BLUE • Absorption - GREEN • Excretion - RED

Step 1
The digestive system can be broadly divided into two main categories: the alimentary canal (gastrointestinal tract) and the accessory digestive organs. The alimentary canal includes organs through which food actually passes (mouth, esophagus, stomach, small Show more…

In a Word document (or the same document that you have been using for parts 1 and 2), please take the overall categories (mouth, small intestine, esophagus, stomach, and large intestine) and label them with the appropriate mechanisms that occur in each of them (propulsion, absorption, chemical digestion and mechanical digestion). Please remember that each digestive system part mentioned above may be involved in more than one of the mechanisms. Please define each mechanism (propulsion, absorption, chemical digestion and mechanical digestion) with 2-3 sentences each.

Please match the function of the digestive system with its description. 1. The combined processes of ingestion, mastication, deglutition, peristalsis, and segmentation 2. Exocrine and endocrine substances 3. The breakdown of food into smaller subunits for absorption 4. The passage of digested products into blood or lymph 5. Temporary storage and subsequent removal of digested molecules 6. Epithelium of the digestive system prevents penetration of pathological organisms and toxins Word Bank: Digestion Secretion Immune barrier Motility Absorption Storage and elimination
