    What are functions of the large intestine?

  • mucosa, submucosa, muscularis externa, serosa

    Order the layers of the esophagus from innermost to outermost.

  • mucosa

    -consists of a surface epithelium and an underlying connective tissue call lamina propria.

  • cardia, fundus, body, pylorus

    What are the 4 regions of the stomach?

  • cardia

    -is the region of the stomach immediately surrounding the junction of the esophagus with the stomach. 

  • fundus

    -is the region of the stomach superior to the gastroesophageal junction

  • body

    -is the largest region of the stomach and lies between the fundus and the lower curving segment of the J. 

  • pylorus

    -has thick wall with strong frequent peristaltic contractions that mix and propel food into the duodenum

    -is responsible for gastric emptying into duodenum

  • cardiac sphincter

    cardia is separated from the esophagus via

    a) cardia

    b) fundus & body

    c) pyloric region

    d) all of the above

  • b,c

    a) cardia

    b) fundus & body

    c) pyloric region

    d) all of the above

  • a,b

    Which region(s) of the stomach contain parietal cells?

    a) cardia

    b) fundus & body

    c) pyloric region

    d) all of the above

  • c

    Which region(s) has glands primarily made of mucus-secreting cells?

    a) cardia

    c) pyloric region

    d) all of the above

  • D cells

    Somatostatin-secreting cells =

  • G cells

    Gastrin-secreting cells =

  • intrinsic factor

    -a substance necessary for absorption of vitamin B12

  • parietal cells

    -secrete HCL & intrinsic factor

  • chief cells

    -secrete pepsinogen

    -gets converted to active form, pepsin, by acids of stomach

  • gastrin

    -stimulates gastric juice secretion and gastric motility
