  9. PERISTALSIS
    THE INVOLUNTARY MUSCLE THAT MAINTAINS THE MOVEMENT OF FOOD THROUGH THE BODY
  10. CARDIAC SPHINCTER
    THE CIRCULAR MUSCLE AT THE UPPER OPENING TO THE STOMACH. OPENS TO LET FOOD IN, CLOSES TO KEEP FOOD IN.
  11. SIZE OF STOMACH
    10 INCHES LONG
  12. HYDROCHLORIC ACID
    MIXES INTO THE BOLUS TO BREAK IT DOWN
  13. PEPTIC ULCER
    HYDROCHOLORIC ACID WILL CAUSE THIS, IF ACID IS LEFT IN STOMACH TOO LONG.
  14. CHYME
    SEMI LIQUID STATE OF FOOD. (THIS HAPPENS AFTER 3-5 HOURS)
  15. PHYLORIC SPHINCTER
    AT THE END OF THE STOMACH AND ALLOWS THE CHYME TO ENTER IN SMALL AMOUNTS TO THE SMALL INTESTINE.
  16. SMALL INSTESTINE
    1" IN DIAMETER AND 20 FEET IN LENGTH. IT COMPLETES THE DIGESTIVE PROCESS AND ABSORBS THE NUTRIENTS FROM THE CHYME.
  17. THREE SECTIONS OF SMALL INTESTINE:
    • DUODENUM: FIRST SEGMENT, 9 INCHES LONG
    • JEJUNUM, 8 FEET LONG
    • ILEUM 12 FEET LONG
  18. THE LIVER
    THE LARGEST GLAND IN THE BODY, LIES BELOW THE DIAPHRAGM INT HE RUQ OFTHE ABDOMEN. IT SECRETES BILE. IT ALSO STORES GLYCOGEN, A FORM OF GLUCOSE
  19. GALLBLADDER
    A SMALL SAC ATTACHED TO UNDER THE LIVER. ITS SOLE PURPOSE IS THE CONCENTRATION AND STORAGE OF BILE.
  20. CHOLELITHIASIS
    GALLSTONES, THIS OBSTUCTS THE BILE DUCTS.
  21. JAUNDICE
    WHEN BILE IS ABSORBED INTO THE BLOOD STREAM, PRODUCING THE YELLOW DISCOLORIZATION.
  22. CHOLECYSTECTOMY
    REMOVAL OF GALL BLADDER
  23. PANCREAS
    LIES BEHIND THE STOMACH, A GLAND. SECRETES INSULIN DIRECTLY INTO THE BLOODSTREAM
  24. LARGE INTESTINE
    WHERE THE WASTE PRODUCTS, UNDIGESTABLE MATERIALS ARE SENT THROUGH THE ILEOCECAL VALVE. 5 FEET LONG, 2" IN DIAMETER
  25. SIGMOID
    ONCE THE LARGE INTESTINE ENTERS THE PELVIC CAVITY IT MAKES TWO TURNS IN THE SHAPE OF AN S...THEREFORE CALL SIGMOID SECTION OF THE COLON.
  26. GASTROSCOPY (EGD)
    VIEWING OF THE ESOPHAGUS, STOMACH AND UPPER DUODENUM THROUGH A FLEXIBLE SCOPE.
  27. PROCTOSCOPY
    EXAMINATION OF THE LOWER RECTUM AND ANAL CANAL THROUGH A 3 INCH LONG PROCTOSCOPE
  28. SIGMOIDOSCOPY
    EXAMINATION TO VIEW THE LOWER PORTION OF THE SIGMOID AND RECTUM THROUGH A 10-12" SIGMOIDOCOPE
  29. APPENDICITIS
    INFLAMMATION OF THE APPENDIX
  30. CIRRHOSIS
    DISEASE OF THE LIVER, CAUSES DESTRUCTION OF THE LIVER CELLS. THIS LEADS TO IMPAIRED BLOOD AND LYMPH CIRCULATION AND INTERFERES WITH THE LIVERS JOB
  31. COLITIS
    INFLAMMATION OF THE COLON
  32. COLOSTOMY
    ARTIFICIAL OPENING OF THE COLON, WASTE IS EXCRETED FROMTHE ABDOMINAL WALL
  33. CRHONS DISEASE
    INFLAMMATION OF ANY PORTION OF THE GI TRACT, MOST COMMON IN THE TERMINAL ILEUM.
  34. DIVERTICULOSIS
    BULGING POUCHES IN THE WALL OF THE GI TRACT
  35. ESOPHAGEAL VARICES
    DILATED, TORTUOUS VEINGS IN THE LOWER SECTION OF THE ESOPHAGUS
  36. FISSURE OF THE ANUS
    CRACK OR TEAR IN THE LINING OF THE ANUS
  37. GASTROENTERITIS
    INFLAMMATION OF THE STOMACH AND INTESTINES. (INTESTINAL FLU, TRAVELERS DIARRHEA OR FOOD POISONING)
  38. GERD (GASTROESOPHAGEAL REFLUX DISEASE)
    BACKFLOW OF GASTRIC CONTENTS INTO THE ESOPHAGUS THROUGH THE SPINCTER JUST ABOVE THE STOMACH
  39. HEPATITIS
    INFLAMMATION AND INFECTION OF THE LIVER THAT CAN RESULT IN CELL DESTRUCTION AND DEATH.
  40. HERNIA
    THE PROTRUSION OF A INTERNAL ORGAND THROUGH A NATURAL OPENING OF THE BODY WALL
  41. HERNIORRHAPHY
    THE PROCEDURE THAT REPLACES THE CONTENTS OF THE SAC
  42. ILEOSTOMY

  43. PANCREATITIS
    INFLAMMATION OF THE PANCREAS
  44. PARALYTIC ILEUS
    USUALLY OCCURS IN SMALL INTESTINE, INTESTINAL OBSTRUCTION. VOMITING, STOMACH PAIN
