Patho Unit 9 Flashcards
neurotransmitter that excites gut activity
acetylcholine
neurotransmitter that slows down gut activity
catecholamine
stimulates gut activity and secretions, made by enterochromaffin
5HT (serotonin
second tissue bed that blood goes through from veins from the intestines before going back to the heart
liver (first pass effect)
fingerlike projection
villus
absorption in small intestines is carried out by
villus structures
nervous system that causes venous constriction with heavy exercise or shock
sympathetic (don’t swim after eating
nervous system that causes dilation after eating a meal
parasympathetic
nervous system that causes dilation after eating a meal
parasympathetic

deglutition
once a bolus is mixed with stomach “juices” it is called…

when stomach is empty for several hours
hunger contractions
12-24 hours after last meal, (fasting) the the pain is worse by 3-4 days then weaken and person no longer feels hungry
hunger pangs

hunger pangs
rapid movement through the small intestine (seen in diarrhea)
peristaltic rush
strong contractions of the colon causing the non constricting parts of the colon to bulge out
haustral contractions
when the lips of the anus pouch outward and the contents of the anal canal are extruded
evagination
accessory organs of digestion
pancreas
liver
gallbladder
when pancreas releases products into the bloodstream
endocrine pancreas
when pancreas sends its products locally to gut for digestion
exocrine pancreas
when pancreas sends its products locally to gut for digestion
exocrine pancreas
salivary glands
submandibular
sublingual
parotid
salivary glands
submandibular
sublingual
parotid
phase of gastric secretion where you are thinking about food
cephalic phase
phase of gastric secretion where food enters the stomach (main stimulus)
gastric phase
phase of gastric secretion with duodenal gastrin and amino acid absorption
intestinal phase
phase of gastric secretion with duodenal gastrin and amino acid absorption
intestinal phase
means there is no demonstrable anatomic or physical/biochemical problem
functional
means there is an anatomical or physical/biochemical problem
organic
means there is an anatomical or physical/biochemical problem
organic
tumor of pancreas that secretes insulin and causes severe hypoglycemia
insulinoma
