1. Pancreas and Nutrition

4. Pancreas Functions: 1. Exocrine 2. Endocrine

5. Pancreas Exocrine: Secretes into ducts, dumps into duodenum. 3 big Ezymes?

6. EXOCRINE 1. Trypsin – works on proteins 2. Lipase – works on fats 3. Amylase – works on Carbohydrates (starch)

7. ENDOCRINE ENDOCRINE: Secretes hormones into blood stream.

9. ENDOCRINE 1. Insulin: Decrease glucose in blood: A) Allows cells to take in glucose B) glucose  glycogen

10. ENDOCRINE 1. Glucagon: INCREASE glucose in blood: A) Glycogen  glucose B) Cell release glucose into blood stream

11. DISORDERS Diabetes: High blood sugar There are two types

12. DIABETES Type I: Lack functioning insulin, presents wrong message, genetic

13. DIABETES Type II: Cells do not respond to insulin, partially genetic, mostly environmental

14. NUTRITION

15. Nutrients: Things in food that promote health

16. NUTRITION calories: Amount of energy needed to raise 1 gram of water 1° (degree) Celsius - A unit of energy.

17. NUTRITION 1 Kilocalorie = 1000 calories 1Kcal = 1 Calorie

18. Carbohydrates Contain C, H, O Quickest form of energy Simple: only has sugar Complex: Sugars + fiber + other stuff.

19. Carbohydrates Energy: 4.1 Kcals gram

20. LIPIDS Highest energy source 9.3 Kcals gram

21. Proteins Good energy, but harder to use then carbohydrates 4.1 Kcals gram

22. Vitamins and Minerals NO ENERGY But you need them for coenzymes

23. OTHERS Water: Used to dissolve things

24. Fiber Prevents Colon cancer, keeps things moving along through the L.I.
