  1. A muscular fiber that guards the opening into the stomach

  6. 3 parts of the stomach
    fundus- upper part
    corpus- center part
    antrum- lower distal part
    • 3 parts of the stomach
    • fundus- upper part
    • corpus- center part
    • antrum- lower distal part
  7. the area on the lower portion of the stomach where the convex curve is. The Greater Omentum provides the blood supply to the stomach. The Greater Omentum covers and protects the intestines
    Greater Curvature
  8. the area on the upper portion of the stomach where the concave curve is located. the Lesser Omentum provides the blood supply to the stomach. The Lesser Omentum extends up to the liver
    Lesser Curvature
  9. the small intestine lies distal to the stomach. it extends from the pylorus of the stomach to the cecum of the large intestine. this is where the largest amount of digestion takes place. from the proximal to distal, the small intestine includes the duodenum, jejunum, and ilium. it is approx. 21 feet long. 1-1.5 inches around.

    mucosa- inner lining
    tissue layers of the large and small intestine
  11. the first (proximal) part of the small intestine extending from the pylorus to the jejunum. it is 12" long.
    duodenum
  12. landmark of the junction of the duodenum and the jejunum
    ligament of treitz
  13. the second part of the small intestine. it is approx 8 feet long. there is no name for the junction between the jejunum and the ileum
    jejunum
  14. junction between ileum and cecum (large intestine)
    illeocecal valve
  15. the third part of the small intestine. it is approx 12 ft long. the ileum then enters the large intestine. the large intestine lies distal to the small intestine
    ileum
  16. aka colon or large bowel, the large intestine extends from the ileum to the anus and is approximately 5' long. it starts at the right side of the body, then transverses to the left side. it consists of the cecum, colon and the rectum
    large intestine- about 3-4 inches around
  17. attached to the cecum, it has no known function
    appendix
  18. mesentery around the appendix that provides the blood supply to the appendix
    mesoappendix
  19. artery that nourishes the appendix
    appendicular artery
  20. consists of 5 sections and two junctions. it extends from the cecum to the rectum.
    colon
  21. cecum; ascending colon; transverse colon; descending colon; sigmoid colon
    5 sections of the colon
  22. hepatic flexure; splenic flexure
    two junctions of the colon
  23. the first part of the colon, approx 3" long
    cecum
  24. second part of the colon, from the cecum it proceeds upward and vertically along the right side of the body toward the liver
    ascending colon
  25. junction at the bend of the ascending colon and the transverse colon (under the liver).
    hepatic flexure
  26. third part of the colon. it proceeds horizontally across the body toward the spleen
    transverse colon
  27. junction at the bend of the transverse and descending colon (under the spleen)
    splenic flexure
  28. fourth part of the colon. it proceeds downward along the left side of the body
    descending colon
  29. fifth part of the colon. it proceeds to the rectum. it is S shaped.
    sigmoid colon
  30. segment extending from the sigmoid colon to anal canal
    rectum
  31. canal that extends to the anus
    anal canal
  32. the posterior opening (sphincter) controlling bowel evacuation
    anus
  33. largest organ in the body which secretes bile and filters blood. the bile is transported by the hepatic duct, to the cystic duct, to the common bile duct, to the duodenum. the liver is located in the upper right quadrant beneath the diaphragm
    liver
  34. a vessel in the upper middle region of the abdomen
    epigastric vessel
  35. serves as a principal attachment of the liver to the diaphragm
    falciform ligament
  36. a membranous muscular sac in which bile from the liver stored. it is located on the inferior side of the liver
    gallbladder
  37. carries bile from the liver to the cystic duct to the gallbladder
    hepatic duct
  38. carries from the liver to the cystic duct to the gallbladder
    hepatic duct
  39. carries bile to and from the gallbladder
    cystic duct
  40. primary blood supply of the gallbladder
    cystic artery
  41. carries bile from the cystic duct to the duodenum
    common bile duct
  42. opening at the duodenum where bile leaves the common bile duct and enters the duodenum
    ampulla of vater
  43. sacculation of the neck of the gallbladder
    hartmanns pouch
  44. two major functions- the exocrine function is to secrete pancreatic fluid into the duodenum used during digestion; the endocrine function is to secrete insulin and it is located in the cavity of the C-shaped section of the duodenum. It is a fish shaped organ
    the pancreas
  45. destroys red blood cells, creates new ones, stores blood components and produces lymphocytes. it is located in the upper left quadrant and is connected to the tail of the pancreas
    spleen
  46. a surgical procedure to remove all or part of the sigmoid colon, rectum, anus. the perineum is closed using suture and permanent colostomy is created
    adbominal perineal resection
  47. excision of the antrum of the stomach (last part)
    antrectomy
  48. surgical removal of the appendix
    appendectomy
  49. removal of part of the intestine. usually followed with an anastomosis, ileostomy or colostomy

    ileostomy
  62. resection of the lower colon and proximal rectum with anastomosis of the remaining colon to the distal rectum
    low anterior resection
  63. excise a piece of the perioneum for examination
    peritoneal biopsy
  64. removal of all or part of the sigmoid colon
    sigmoid colectomy
  65. resection of the spleen. simple procedure however removal is serious
    splenectomy
  66. anything less than total resection of the stomach
    subtotal gastrectomy
  67. excise a piece of the peritoneum for examination
