  • Digestive System Digestive System
  • Digestive System Mouth chewing and crushing digestion begins saliva - > digest starch
  • Digestive System Stomach Grinds and churns Chyme Release HCl Protein digestion
  • Low pH Stomach Low Ph Uncoil protein Mucus released Protects stomach cells
  • Digestive System Intestines Digestion Absorption Release enzymes
  • Digestive System Pancreas CHO digesting enzymes Protein digesting enzymes Fat digesting enzymes
  • Digestive System Liver Produces bile
  • Digestive System Gallbladder Releases bile
  • Digestive System Colon Absorbs water Absorbs minerals Some fiber digested
  • Storage Systems Liver Muscle Fat cells
  • Storage Systems: Carbs Starch Glucose Glycogen • Liver • Muscle Fat cells
  • Storage Systems: Fat Fat Fatty Acids Fat cells
  • Storage Systems: Protein Protein Amino Acids NOT STORED! Fat cells
  • heartburn antacids more acid!
  • Drink before and after meals Limit fiber Smaller meals, more often Loose clothing Don’t lie down after eating
  • Alcohol Positive (moderation) Negative (excess)
  • THE remarkable body END
