1. Digestive system Matspjälkningsapparaten Catherine Mortimer-Hawkins, Edsbergsskolan

3. proteins (proteiner) for growth and repair;

4. fats (fetter) to store energy;

6. But how does a 9m tube fit into a space, which is less than a metre long? The digestive system is really one long tube with an opening at each end. Stretched out it is a 9m tube! mouth anus

7. Okidoki!! Let’s go for a ridethrough your body!

8. Digestion begins in the mouth where food is broken down by the teeth. This is called mechanical breakdown. The small parts of food are mixed with saliva and swallowed.

11. Duodenum - tolvfingertarm Here the digestedfood is mixed with bile from the gallbladder and juices from the pancreas. The bile: Breaks up larger fat drops to smallerdroplets The juices from the pancreas: Neutralize the acid from the stomach Mix the digestedfood with enzymes

12. Enzymes sugar molecules Pepsin long carbohydrate molecule + glycerol long proteinmolecule amino acid molecules Lipas fatty acids Amylas

13. The small intestine It is in the small instestine the small molecules gets through the thinwalls and reaches the bloodvessels. The walls are folded in so calledvilli (tarmludd).

14. The largeintestine Here in the largeintestine water is sucked back into the body. If this doesn’t work… then you get diarrhea. Colibacterialives in the largeintestine and helpmaking K-vitamins. Theyhelp with the last of the digestion and thenalso make methane gas…. …a fart in otherwords!

15. The anus The ex-foodleaves the body through the anus. When the pooreaches the anus signals are sent to the brain to relax the musclesand the poo is pressed out.

17. enzyme –A chemical that helps digestion by breaking large molecules into smaller ones.

18. fat – A nutrient in food that provides a store of energy.

19. large intestine –The organ where water is removed from undigested food.

20. minerals –Compounds infood that provide the elements needed in small amounts for a healthy diet.

21. protein –A nutrient in food needed for growth and repair.

22. small intestine –The organ where digestion is completed and digested food molecules are absorbed.

23. stomach –The organ where food is mixed with acid and enzymes.

24. vitamins –Substances found in food that are needed in
