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?
Today’s Agenda Science Starter Yesterday’s Notes… Organ Poster Review Graphic Organizer & Study Guide Dissection Prep
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)
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
How to improve metabolism? Lift Weights Sleep More Drink Water Drink Caffeine Eat Protein
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)
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
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
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!
