Anatomy. 1
duodenum, jejunum and ileum
enzymes that break down protein
proteases
ion that plays a big part in smooth muscle contraction
Ca2+/ calcium ions
type of epithelium found in small and large intestine
simple columnar epithelium
cell that secretes HCL
parietal cells
the beginning of the large intestine
caecum/ cecum
main enzyme in saliva
amylase
what small triaglycerol particles are covered in to prevent re-aggregation
bile salts & other amphipathic lipids
longitudinal strands of muscle that contract to move faecal matter along the large intestine
taenia coli
anagram for "clench oily tea"
acetylcholine
artery that supplies both intestines
superior mesenteric artery
where absorption of nutrients mostly occurs
small intestines
what triaglycerols are broken into
2-monoglycerols and free fatty acids
part of small intestine that has more mesenteric fat
ileum
creates a raft on gastric acid that acts as a barrier, stopping gastro-oesophageal reflux
gaviscon
bend where the ascending colon and transverse colon meet
right colic flexure/ hepatic flexure
3 monosaccharides that can be absorbed into bloodstream
fructose, galactose, glucose
two patterns of GI contraction
peristalsis and segmentation
receives the common bile duct and pancreatic duct
descending duodenum
is an antispasmodic agent
hyoscine butylbromide
below this line the epithelium is stratified squamous non-keratinising
pectinate line
two ways carbohydrates are taken into the circulation
active transport & facilitated diffusion
type of contraction that consist of brief periods of relaxation and contraction
=> happens in stomach & small intestine
phasic contraction
2 inch long vestigal remnant of the vitelline duct
meckel's divertum
indications for hyoscine butylbromide
abdominal cramping, bowel cholic, irritable bowel syndrome
