5. Bio 9C: Monday, 11.22.10 Title: Digestive System: Structures & Functions • Homework: • Digestion Review Questions • Pass Revised McMush Lab Reports • Do Now: • Describe the structure and function of the following objects • Today’s Objectives: • Describe the difference between structure and function, and explain how an object’s structure relates to its function • Describe the structures and functions of digestive system organs, and explain how they relate to each other

6. Debrief Do Now: • Function: • Hold/contain/store things • Relate structure to function: • Sack-like shape with space inside to hold stuff • Drawstring opening can open to receive things, and close so they don’t fall out • Similar digestive organ: • Stomach • Function: • Dry things by absorbing water • Relate structure to function: • Cotton material is very absorbent • Tiny strings on surface provide more space for absorbing stuff • Similar digestive organ: • Small intestine • Function: • Crush things • Relate structure to function: • Hinges allow it to open to receive things & close to crush them • Metal provides hard crushing surface • Ridges prevent things from slipping out • Similar digestive organ: • Mouth

7. MOUTH Structure: Mechanical Digestion/Absorption: Chemical Digestion: Structure-Function Connection: ESOPHAGUS Structure: Mechanical Digestion/Absorption: Chemical Digestion: Structure-Function Connection: Hinged jaws, hard teeth, muscular tongue Long muscular tube Pushes food from mouth to stomach by peristalsis (waves of muscle contraction) Crushing, grinding, moistening food Proteinpepsin Peptides Starch salivaryamylase Glucose None Muscles help squeeze food down the tube Jaws open & close to crush; hard teeth grind; tongue mixes food w/ saliva LIVER Major Function: STOMACH Structure: Mechanical Digestion/Absorption: Chemical Digestion: Structure-Function Connection: Makes bile for lipid digestion in small intestine Muscular sac containing acids & enzymes Food churned/mixed with acids & enzymes; acids kill bacteria & loosen food particles GALLBLADDER Major Function: Stores and releases bile into small intestine PANCREAS Major Function: Muscles in stomach walls contract to churn food Makes enzymes for small intestine

9. Bio 9C: Tuesday, 11.23.10 Title: Digestion Project Work Time • Homework: • Complete up to step 3 on the digestion project by Monday! • Do Now: • Which organ is the most confusing to you right now? Why? If this isn’t addressed by the end of class, ask the question! • Today’s Objectives: • Follow carbohydrates, proteins, and lipids through the digestive system. • Decide on the creative form your project will take, and begin writing.

SMALL INTESTINE Structure: Chemical Digestion: Mechanical Digestion/Absorption: Structure-Function Connection: LARGE INTESTINE Structure: Chemical Digestion: Mechanical Digestion/Absorption: Structure-Function Connection: Long narrow tube with millions of folds (villi) and hairs (microvilli) Wide tube w/ many bacteria living there Bacteria break down wastes and release vitamins Starch amylase Glucose Lipids lipase Fatty acids & glycerol Disaccharides Monosaccharides Peptides peptidase Amino acids Protein trypsin Peptides Water and vitamins absorbed into bloodstream Waste is solidified and compacted Width of tube provides space for waste to build up and get compacted ANUS Major Function: Bile breaks up lipid globs Villi absorb all nutrients/monomers into the bloodstream (glucose, amino acids, fatty acids…) RECTUM Major Function: Store digestive waste (feces) Long tube + villi/microvilli provide a lot of surface to absorb all the nutrients. Release feces from the body ZOOM IN ON THE SMALL INTESTINE!

13. The Creative Portrayal of the Digestive System The Project: Follow the journey of some food through the digestive system from the perspective of the food. • Choose a food that contains the following organic compounds: carbohydrates, protein, and lipids. • Trace the path of that food as all of its components are digested.  You will portray this journey in ONE of TWO ways (you choose ONE): • Creative Writing: Write a creative story from the perspective of the food. Describe your journey through the digestive system. • Illustrated Storybook: Combine the above option with some illustrations to trace the path of the food through the digestive system. You might want to describe each major component of the digestive system on a different page (Hint: a great way to do this would be to create the story in PowerPoint, so that each slide is a page). Your project should illustrate the following big ideas: • The relationship between structure and function in the human digestive system • The process of breaking down food into small, building block molecules • The importance of enzymes in metabolism

14. The Creative Portrayal of the Digestive System Day 1 • Digestion Project Overview • Begin Digestion Project • Complete Step 1 • Be specific when identifying the sources of carbon compounds in your meal. • Complete up to Step 3 for the start of Monday’s class. • Pay close attention to how the carbon compounds are broken down from the complex polymers to the simplest monomers that are absorbed into the blood stream. How many stages does it take for each to do this? • Objectives for Class: • Describe the structures and functions of digestive system organs, and explain how they relate to each other • Explain the purpose of the Digestion Project and identify what meal you will use.

15. Bio 9C: Monday, 11.29.10 Title: Digestion Project Work Time • Homework: • Rough draft of Digestion Project due Wednesday, 12.1.10 at the start of class! Final Drafts are Due Thursday. • Do Now: • Take out your digestion project packet • Turn to the outline in the Digestion Packet (the end of Step 2) and wait until the next slide. • Today’s Objectives: • Follow carbohydrates, proteins, and lipids through the digestive system.

16. The Digestion Project:The Creative Portrayal of the Digestive System Before moving on from Step 2: • Get 3 colored pencils • In the chart for Step 2… • Choose one color for carbs.Circle all the chemical digestion that involves carbsin that color. • Choose another color for proteins. Do the same thing. • Choose a 3rd color for lipids. Do the same thing. Next Steps: • Organize your notes and story outline • Begin writing the story (completed rough draft due Wednesday)
