abdominal viscera Flashcards
what is the greater sac
main abdominal cavity
what is the lesser sac
omental bursa
diverticulum
what is intraperitoneal
- enclosed by visceral peritoneum
- suspended by mesenteries
what is in the greater omentum
gastrophrenic lig
gastrosplenic lig
gastrocolic lig
what is in the lesser omentum
hepatogastric lig
hepatoduodenal lig
what is the function of the abdominal viscera
primarily digestive
spleen, kidney, adrenal glands
what is in the lower thoracic cage
stomach
liver
spleeen
what does the esophagus do
- transports food to stomach
- helps warm/cool food
- can expand significantly
- thick muscular walls produce strong peristaltic waves
- muscular walls transition from skeletal to smooth muscle
what is the composition of the esophagus
-muscular coat; longitudinal and circular
upper 1/3 skeletal
middle 1/3 smooth and skeletal
lower 1/3 smooth
what is the innveration of the espohagus
R and L vagus nn
- upper= recurrent laryngeal
- below lung roots= esophageal plexus
what does the stomach do
- stores food
- HCI disinfects the food and denatures protein
- HCI activates protease pepsin
- produces chyme that is released in peristaltic spurts into the duodenum
what does the small intensine do
- enzymatic digestion of food
- abroption of nutrients
what are the parts of the small intenstine
duodenum
jejunum
ileum
what does the liver do
- receives blood from digestive system
- detoxifies and removes debris
- stores glucose in form of glycogen
- produces plasma proteins
- exxhanges metabolities with blood
- produces bile
what does the gallbladder do
- stores and concentrates bile produced by liver
- releases bile in response to chyme entering duodenum
- bile emulsifies fats and enhances their digestion and absorption
- consists of bilirubin, cholesteral, water and ions
what does the pancreas do
- produces a variety of enzymes
- produces a bicarbonate solution to help liequefy and neutralize acidic chyme in the duodenum
- endocrine organ
what does the large intensitne do
- absorb water and minerals
- no digestions
- harbor lots of bacteria
- has incomplete longitudnal layers

the HPV passes ___ to the epiploic foramen, and in the lesser omentum, it is typically positioned ____ to the bile duct and the hepatic artery proper
anterior, posterior
hepatic artery proper passes ___ to the epiploic foramen
anterior
R renal artery passes directly ____ to the IVC
posterior
R testicular artery passes directly __ to the IVC, R ureter, and the psoas
anterior
R common iliac artery passes direcrtly ___ to left common iliac
anterior
obturatory a,v,n pass ____ to the superior pubic ramus
inferior
what is the hilum
external on kidney
where the renal a,v, and ureter is
what is in the internal kidney
- cortex
