1. Science Starter How many organs are there in the digestive system?
Which organs are involved in mechanical digestion?
Which organ does the majority of the digestion?
What is the difference between the small intestine and large intestine?
Which organ is associated with diabetes?

2. Today’s Agenda Science Starter Yesterday’s Notes… Organ Poster Review
Graphic Organizer & Study Guide
Dissection Prep

3. Nutrition, Metabolism, & Energy
Essential nutrients supply energy (calories) and supply the necessary chemicals which the body itself cannot synthesize (create)
The diet needs essential nutrients
Metabolism: chemical reactions in the body (anabolism and catabolism)

4. Slow Metabolism Inactivity is the main cause of a slow metabolism
Dieting or cutting calories also lowers your metabolism over time
As the body's cells age, they slow down the pace at which they use energy

5. How to improve metabolism?
Lift Weights
Sleep More
Drink Water
Drink Caffeine
Eat Protein

6. Organ Poster Review
Choose a partner and an organ in the digestive system
Design a poster on your organ to share with the class
These posters will be used to fill out your study guide!
Make sure they are informative, correct, and aesthetic!
Include the following:
Drawing of organ (or picture)
Associated organs (connections)
Function (mech vs. chem), enzymes, important structures, etc..
Malfunction (role in digestive system health)

7. Cecum & Appendix
The main functions of the cecum are to absorb fluids and salts
It receives chyme from the ileum
Appendix- may play a role in the immune system in addition to the digestive system (not vital)
Malfunctions
Appendicitis- inflammation due to bacteria causing pain
Irritable Bowl Syndrome- sensitivity to food items

8. Colon 3 parts: Ascending, transverse, and descending
Its function is to reabsorb fluids and process waste products from the body and prepare for its elimination.
Toxic megacolon occurs as a complication of inflammatory bowel disease
Colon Cancer
Dehydration and constipation are due to problems with water absorption

9. Graphic Organizer & Study Guide
Fill out the front (graphic organizer) using the posters created in class today
After you fill out the organizer, use the information to answer the study questions on the back
Study this information and turn in the study guide on Friday!
If you finish, visit my website and look at the rat dissection links. Watch the video and prep for tomorrow!
