8. What nutrients are needed for your body to function? Food (carbohydrates, lipids, proteins, vitamins, minerals) Water Oxygen

9. NUTRIENT ABSORPTION DigestiveRespiratoryCirculatory SYSTEMS INVOLVED DRAW ALL OF THIS.

10. DIGESTIVE SYSTEM Main Parts: Mouth Esophagus Stomach Small intestine Large intestine

11. Getting & Using Food Ingest taking in food Digest mechanical digestion breaking up food into smaller pieces chemical digestion breaking down food into molecules small enough to be absorbed into cells using enzymes Absorb absorb nutrients across cell membranes diffusion active transport Eliminate undigested material passes out of body intracellular digestion extracellular digestion

12. Digestive systems Everybody’s got one!

13. stomach  kills germs  break up food  digest proteins  store food sphincter mouth  break up food  digest starch  kill germs  moisten food

14. stomach  kills germs  break up food  digest proteins  store food mouth  break up food  digest starch  kill germs  moisten food pancreas  produces enzymes to digest proteins and starch

15. pancreas  produces enzymes to digest proteins & starch stomach  kills germs  break up food  digest proteins  store food mouth  break up food  digest starch  kill germs  moisten food liver  produces bile - stored in gall bladder  break up fats

16. small intestines  breakdown food - proteins - starch - fats  absorb nutrients stomach  kills germs  break up food  digest proteins  store food mouth  break up food  digest starch  kill germs  moisten food pancreas  produces enzymes to digest proteins and starch liver  produces bile - stored in gall bladder  break up fats

17. stomach  kills germs  break up food  digest proteins  store food mouth  break up food  digest starch  kill germs  moisten food small intestines  breakdown food - proteins - starch - fats  absorb nutrients pancreas  produces enzymes to digest proteins and starch liver  produces bile (stored in gall bladder)  break up fats large intestines reabsorb water

18. DIGESTIVE SYSTEM Main Functions: Mouth breaks down food into smaller pieces Stomach enzyme breaks food into biomolecules (carbs, lipids, proteins) Small intestine breaks food into monomers and absorbs nutrients Large intestine reabsorbs water

20. Lung Inflation! How Lungs Work!

21. RESPIRATORY SYSTEM Main Parts: Nose Mouth Lungs Diaphragm

22. RESPIRATORY SYSTEM Main Functions: Nose & mouth filter air as it comes in Diaphragm contracts and relaxes to move the lungs Lungs expand and contract for inhaling & exhaling Oxygen diffuses into blood Oxygen necessary to release energy from food (glucose)

24. Circulatory System

25. CIRCULATORY SYSTEM Main Parts: Blood vessels Heart Red blood cells

26. The Heart Left Ventricle Left Atrium Right Atrium Right Ventricle valve Vein from Lungs Artery to Head and BodyArtery to Lungs Vein from Head and Body valve

28. what’s in red blood cells white blood cells platelets plasma carbon dioxide digested food waste (urea) hormones oxygen

29. Red Blood Cells contain hemoglobin, a molecule specially designed to hold oxygen and carry it to cells that need it. can change shape to an amazing extent, without breaking, as it squeezes single file through the capillaries. a biconcave disc that is round and flat without a nucleus

30. CIRCULATORY SYSTEM Main Functions: Heart pumps blood through blood vessels Transports oxygen & carbon dioxide to and from the respiratory system Transports nutrients from the digestive system to the rest of the body

32. INTERACTION: Maintaining Homeostasis Balancing glucose levels in blood pancreas insulin liver takes up glucose for storage cells take up glucose from blood liver releases glucose to blood depress appetite stimulate hunger glucagon

33. DEBRIEF : Explain how all three systems work together for nutrient absorption in the body.
