  1. Greater omentum
    • Drapes like an apron over abdomen

    • Largest internal organ
    • 2 lobes in humans
    • Removes toxins from blood
    • Breaks down lipids

    • More closely linked to the lymph system; not part of the digestive system
    • Processes old red blood cells
  4. Gallbladder
    • Connected to liver
    • Stores bile, bile pigments and cholesterol
  5. Stomach
    • J-shaped in humans; gastric folds rugae
    • Excretes gastric juice (pepsi, initiates digest of protein
  6. Pancreas
    • Closely associated with s.i.
    • Pyloric sphincter leads to the s.i.
    • Secretes pancreatic juice, contains enzymes to digest carbohydrates, fats
  7. Small Intestine
    • Duodenum (start/short), jejunum (middle/bigger), ileum (end, lymph nodes)
    • Many impt. metabolic activities Carb. -> maintain blood sugarLipids and proteinDestroys old RBCsStores many vitamins? A, D, B12, extra iron
  8. Large intestine
    • Cecum (start of l. in.)
    • Receives secretions from the pancreas and liver; MOST ABSORPTION, digest. system
    • Little to no digest. function
    • Lots of mucus
    • Absorption of H2O and electrolytes
    • Lots of bacteria
    • Circle(?) of intestinal gas production
  9. Rectum
    • End of the l.in.
    • last section
  10. Anus
    • distal end of the rectum
    • contain sphincter muscles that control the release of waste
  11. Esophagus
    • Collapsible tube 25 cm long
    • Moves food from mouth 2 stomach via peristaltic waves
  12. Mesentery
    Supports blood vessels and nerves that feed s.i.
  13. Alimentary canal
    About 8m long
  14. Pathway of food
    • Tongue
    • Esophagus
    • Stomach
    • S.I.
  15. Compare the types and numbers of teeth present in a cat's upper and lower jaws with those of a human.
    • Cats have 32 teeth - 6 incisors, 2 canines, 8 premolars, and 2 molars (upper jaw); lower jaw same with only 4 premolars
    • Humans - 8 incisors, 4 canines, 8 premolars, 12 molars (32 teeth total)
  16. In what ways do that cat's teeth seem to be adapted to their special diet?
    gnashing and tearing
  17. How do that papillae on the surface of the human tongue compare with those of the cat?
    • Cat are much more pronounced and sharp
    • Used for cleaning
  18. Compare the structure of the human liver with the cat.
    • Human - 2 lobes
    • Cat - 5 lobes
  19. What feature of the human cecum is lacking in the cat?
    Appendix
  20. Diaphragm
  21. Gallbladder
  22. Greater omentum
  23. Heart
  24. Left lateral lobe of liver
  25. Left medial lobe of liver
  26. Lung
  27. Right medial lobe of liver
  28. Small intestine
  29. Spleen
  30. Urinary bladder
  31. Bile duct
  32. Descending colon
  33. Diaphragm
  34. Duodenum
  35. Esophagus
  36. Kidney
  37. Lesser omentum
  38. Mesentery
  39. Pancreas
  40. Rectum
  41. Right lateral lobe of liver
