Abdominal Cavity III Flashcards
Lesser sac
behind stomach
Epiploic foramen
opening between 2 sacs
Lesser omentum
attached to liver and stomach, not body wall
What are the two ligaments of lesser omentum
hepatogastric
hepatduodenal
Greater omentum
fatty apron
What are the ligaments of the greater omentum
gastrocolic ligament
gastrophrenic ligament
gastrosplenic ligament
Mesoappendix
connects appendix to cecum and last part of ileum
Dorsal mesocolon
connects the transverse colon
fairly moveable
intraperitoneal
Sigmoid mesocolon
connects descending colon to sigmoid colon
Leinrenal
between kidneys and spleen
Ligaments of liver
ligamentum teres
falicform ligament
coronary ligament
Coronary ligament
attaches liver to diaphram
Tunicae of Digestive tract
mucosa
submucosa
muscularis
serosa
HIstology of esophagus
smooth muscoa to move food down
histo of stomach
gastic pits for acid production
histo of small intestine
villi that absorb nutrients
openings for pancreatic /hepatic ducts
histo of colon
openins for water absorption
FUnction of esophagus
transport
mechanical and some chemical digestion
Muscular layers of esophagus
longtiudinal and circular layers to produce perstalis
Function of stomach
food resevoir
mechanical digestion
secretions that digest proteins (pepsin)
propel chyme
Muscular Layers of stomach
circular
longitudinal
oblique
Function of rugae in stomach
increase surface area and allow stomach to expand in size
Function of small intestine
mainly chemical digestion acid gets neutrilized w/bicarb bile digests fat carbs get digested w/ pancreatic enzymes some absorption
Duodenum
digests iron
c -shaped
has paillae
major duodenal papillae
bile and pancreatic ducts enter
minor duodenal papillae
only pancreatic ducts
jejunum characteristics
reddish thicker walls less mesentric fat larger and frequent pilcae circularis simpler arcades longer vasa rectae
ileum characteristics
pinkish thinner walls more mesenteric fat sparser pilcae circularis many arcades shorter vasa rectae patches of lymph tissue
Large intestine function
absorb water and electrolytes
bacterial digestion (vit K)
more, store, and evacutate feces
Large intestine characteristics
has tenia coli
haustra
less profound plicae circularis
appendix
probably has immune function/storage for commensal organisms
rectum
stores feces
Functions of liver
protein synthesis
bile production and secreteion
carb metabolism (metabolite storage)
detox
lobes of liver
R lobe
caudate lobe
quadrate lobe
left lobe
porta hepatis
hilum of liver
caudate lobe
seperated by IVC
quadate lobe
seperated by gallbladder
Functions of gallbladder
bile storage
bile concentration
bile release
Cystic duct comes from what
gallbladder
Where do common and cystic duct meet from
common bile duct
Functions of pancrease
synthesize/secrete enxymes
deliver pancreatic juice to duodnum
endocrine
Ducts of pancreas
pancreatic duct (comes from dorsal lobe) smaller accessory duct
pancreatic juice is made of what
proteases
lipases
nucleases
amylases
Function of spleen
immuno stuff produce WBC secrete antibodies destroy senscient RBCs recycle chemicals from destroyed RBCs resevoir and rapid deployment of undiff. monocytes
Sliding hernia
cardiac portion of stomach slides up into thorax then back down
intermittent problems/symptoms
paraesophageal hiatus hernia
more portions of stomach enter thorax and stay there
more problems
