Presentation Transcript

  1. SunSupperSweat Convey in 20 words or less, how solar energy transfers to food energy and then to cellular energy (ATP) which is used to do the work of the body.

  2. Photosynthetic magic transfer solar to food energy Tasty meal Cell respiration transfers food energy to cell fuel. Voila, push ups

  3. How Food Becomes You Consumption Digestion Absorption Transport Metabolism

  4. FOOD CONSUMPTION The Fun Part

  5. What factors influence your food choices?

  6. Digestion

  7. What do you think? T/F There is acid in the stomach that could burn your skin. Swallowed gum stays in the stomach about a week. Food really can go down the wrong ‘tube’. A healthy GI tract is clean (sterile). Food is made into ATP in the GI tract.

  8. Gastrointestinal Tract • The Food Tube • Runs through the body • Gatekeeper to the body • Whole foodscomponentparts to be absorbed into bloodstream • Proteins ? • Carbs ? • Fats/Oils ? • Vitamins, minerals, water absorbed ~as is

  9. Digestive Processes of GI Tract Mechanical Chemical Acids Bases Water Enzymes • Relevant terms • Reverse peristalsis • Emulsification • Denaturation • Hydrolysis • Chewing • Peristalsis A delish practical application of a few of these terms

  10. In ‘N Out • ~ 30’ of muscular tube,nerves, secretory organs • Mouth • Esophagus • Stomach • Small Intestine (SI) • Large Intestine (LI) • Rectum/Anus • How long is this ‘trip’?

  11. In ‘N Out • ~ 30‘of muscular tube,nerves, secretory organs • Mouth • Esophagus • Stomach • Small Intestine (helpers) • Large Intestine (LI) • Rectum/Anus • How long does this take?

  12. Digestive Brew Dumps into SI • Liver makes bile to emulsify fat • Gall Bladder concentrates/stores/secretes bile • Pancreas  makes/secretes digestive nz • SI makes digestive nz for digestion

  13. Large Intestine (LI) • Water re-absorption • Good bacteria make ~Vitamin K • aka ‘probiotics’ • Bad bacteria cause sickness • What NOT absorbed… is waste excreted Bacteria and Fiber (↑ fiber ↓ transit time) • What are prebiotics?

  14. Absorption Digestednutrients move thru wall of SI into bloodstream • Carbs as glucose • Protein as amino acids • Fats/oils as chylomicrons (type of lipoprotein) Heart pumps blood to ‘feed’ all cells

  15. Fig. 3-10, p. 81

  16. Nutrient Roadmap What’s next? Consume food Digest Absorb Transport

  17. Nutrient Roadmap Consume food Digest food Absorb nutrients Transport to cell Cells metabolize nutrients… make energy (ATP) build ‘stuff’ store extra calories as fat!!

  18. What do you think now? T/F There is acid in the stomach that could burn your skin. Swallowed gum stays in the stomach about a week. Food really can go down the wrong ‘tube’. A healthy GI tract is clean (sterile). Food is made into ATP in the GI tract.

  19. Summary…howfood becomes you! Digest…..breakdown whole food Absorb….transfer nutrients into blood Transport…. move nutrients to cells Metabolize….cell use or store nutrients Think before you eat…!

  20. Optional slides

  21. Fig. 3-11, p. 82

  22. Misdirected Morsels Fig. 3-13, p. 89

  23. Rate of Digestion p. 85

  24. Rate of Digestion p. 85

  25. Major Organ Roles in Digestion Mouth mechanical is primary carb digestion begins Stomach chemicalis primary protein digestion begins SI #1 site of chemdigest most nutrients absorbed here LI water reabsorbed into blood

  26. Metabolism-what happens in cells • NRG nutrients cell fuel (ATP) • Nutrients perform specific jobs • Excess energy nutrients convert to fat and are stored ….!
