Ingestion and digestion

  1. Enterokinase
    Activates Trypsinogen enzyme
  2. Bicarbonate
    Nutralizes chyme - Deactivates pepsin
  3. Enterogastrone
    Slows peristalsis movement
  4. Large intestine
    Absorbs water, salts, and some vitamins - stores waste until defecation

    stores E. Coli - create Vitamin B, K
  5. Cirrhosis
    Damaged liver tissue gets replaced by scar tissue
  6. Jaundice
    Yellowing of the skin by bile salts produced in liver but cannot get to gall bladder becuase of gall stones
  7. Gall stones
    Bile salts and LDL form blockages in the bile duct
  8. Liver
    Detoxifies blood by filtering substances

    Stores glycogen, vitamin A,B,D
  9. Bile Salts
    Emulsify fats apart

    Made in liver - Stored in gall bladder
  10. Lipase
    Enzyme that digests Lipids

    Made in pancreas - S.I.
  11. Erepsin
    Enzyme that digests proteins

    Erepsinogen --> Erepsin

    Made in pancreas - S.I.
  12. Trypsin
    Enzyme that breaks proteins down

    Trypsinogen --> Trypsin

    Made in pancreas - S.I.
  13. Pancreas
    Nutralize chyme from the stomach - produce enzymes
  14. Lacteal
    Small vessel inside the villi that absorbs fatty acids
  15. Microvilli
    Small formations on the villi - greatly increase surface area for absorbtion
  16. Villi
    Finger like formations on the wall of the small intestine - used to create more surface area for absorbtion
  17. Small intestine
    Chemically digest food and absorbs nutrients - transport undigested waste to the large intestine
  18. Endoscope
    A tube shaped instrament with a camera - used to diagnose problems inside the body
  19. Histamine
    Histamine is produced to try and counter the ulcer but it makes it worse
  20. Ulcer
    The protective layer of mucus breaks down exposing stomach acid to capillary network
  21. Pepsin
    Enzyme that starts protein digestion

    pepsinogen --> Pepsin

    Made in stomach and pancreas - S.I. - Stomach
  22. Hydrochloric acid
    Acid in the stomach - activate pepsinogen - pH (2-3)
  23. Mucous cells
    Secreate mucus so the stomach walls dont get dissolved
  24. Sphincters
    Lower esphogus gate - pyloric exit
  25. Stomach
    Stores food and starts protein digestion
  26. Epiglotts
    The gate that controls movement of food and air to their respective places
  27. Peristalsis
    The rythmic contracions of the esophagus that brings food to the stomach
  28. Amylase enzyme
    Enzyme produced in the mouth that digests carbs
  29. Salivary gland
    Produces amylase enzyme
  30. Egestion
    the removal of undigested materials
  31. Absorbtion
    Cells absorb small molecules
  32. Digestion
    the process of breaking down foods
  33. Ingestion
    Act of eating
