1. Fuel For Your Cells Part 1: What’s for Lunch?

2. Objectives: Students Will: Understand how the digestive system works. Understand how the digestive system works. Describe role of the digestive system in cellular respiration. Describe role of the digestive system in cellular respiration. Complete Part 1 in your packet. Complete Part 1 in your packet. Homework:

3. -Describe and explain that the complex set of systems found in multicellular organisms are made up of different kinds of tissues and organs which are, in turn, composed of differentiated cells -Select several body systems and explain the role of cells, tissues, and organs in the systems selected that effectively carry out a vital function for the organism, such as:Obtaining food and providing energy, Defense, Reproduction, Waste Removal, Breathing VSC Content Standard: Recognize and explain that human beings, like other organisms have complex body systems of cells,tissues, and organs that interact to support an organisms growth and survival.

4. Lesson Question: What role does the digestive system have in cellular respiration? What role does the digestive system have in cellular respiration? * Pages in this PowerPoint will be representing the green books found in school. Page numbers will be different in the blue books you use at home. * Pages in this PowerPoint will be representing the green books found in school.

5. Engage your thinking: Which would your cells choose for lunch? Today’s Lunch Menu: Nitrogen salad topped with sodium dressing….$4.95 Hydrogen sandwich and a bag of chips……….$3.95 Spicy Carbon Dioxide gumbo…………………..$5.95 Creamy Carbon Stew……………………...……$5.95 Glucose steak with a side of Oxygen…….……$6.95 Potassium Nitrate Melt and fries……………….$4.95 Thank You for Choosing the Happy Cell Diner

6. Engage your thinking: Which would your cells choose for lunch? Today’s Lunch Menu: Glucose steak with a side of Oxygen…….……$6.95 Thank You for Choosing the Happy Cell Diner If it were up to your cells to decide, they would choose glucose and oxygen! These are the two raw materials that your cells need to obtain energy. What is the process called that uses glucose and oxygen as raw materials to release energy for cells?

7. Cellular Respiration! http://asm.wku.edu/courses/Biol115/Wyatt/Metabolism/Respiration.gif

8. Let’s explore how the digestive system works! We know that eating food brings glucose into your body, but how does the process of digestion work? Use the website above and your books (pp. 60-71) to answer the following: We know that eating food brings glucose into your body, but how does the process of digestion work? Use the website above and your books (pp. 60-71) to answer the following: 1. What is digestion? 2. Which organs does food pass through after it leaves the mouth? 3.How do food molecules leave the digestive system and enter the blood? 4. Which enzymes help to break down food in your stomach? http://www.sciencebob.com/lab/bodyzone/stomach.gif http://yucky.kids.discovery.com/noflash/body/pg000126.html

9. Let’s explore the organs of the digestive system! We know that your digestive system consists of organs that break down food so that your body can use it, But what organs are a part if this system? We know that your digestive system consists of organs that break down food so that your body can use it, But what organs are a part if this system? Use the website below and your books (p. 61) to explore the parts of the system. As you go, think about what type of muscle tissue makes up most of these structures: Use the website below and your books (p. 61) to explore the parts of the system.

10. Check For Understanding

11. Check Point … Levels of organization for the digestive system The main function of the digestive system is to break down foods into smaller chemicals that your cells can use. The main function of the digestive system is to break down foods into smaller chemicals that your cells can use. The digestive system is made up of organs such as your mouth, esophagus, stomach, small intestine, and large intestine. The digestive system is made up of organs such as your mouth, esophagus, stomach, small intestine, and large intestine. These organs are made up of mostly smooth muscle tissue. These organs are made up of mostly smooth muscle tissue. This tissue is made up of specialized cells that have different jobs (animal cells).

12. Explain: Movement of food… Using your text, (pp.60-71) to create a flow chart to explain the organs that food would pass through as it moves through your digestive system. Be sure to include the following terms: Stomach, Mouth, Large Intestine, Small Intestine, Esophagus

13. Extension… The process of absorption… Use your text (p.70) to answer the following: Use your text (p.70) to answer the following: 1. Why is it necessary for digested materials to enter the blood? Explain. 2. What is the function of villi and how are villi used in absorption? 3. What does your body use these materials for? Explain.

14. Evaluate: How does the process of digestion supply your cells with one of the materials they need to obtain energy for their daily processes ? Please explain using information from your text and our class investigations.

15. Evaluate yourself… Do you: Understand how the digestive system works. Understand how the digestive system works. Can you: Describe role of the digestive system in cellular respiration. Describe role of the digestive system in cellular respiration.
