Accessory Organs Flashcards
Liver
RUQ
Lobes - right, left, quadrate, caudate
Portal triad
Forms cross bar of H
Vein = posterior
Artery = inferior
Bile duct = green
Ligaments of liver
Falficiform splits into right and left lobes
Continuous with coronary and triangular ligaments superior
Ends as round ligament (ligamentum teres hepatis) inferiorly
Ligamentum venosum
Right side of H in liver
Used to be ductus venous
Shunt umbilical vein to IVC
Round ligament
Ligamentum teres hepatis
Used to be umbilical vein
Liver segments
Each receives a branch of hepatic artery and vein
High capacity for regeneration
Nutrition to liver
Almost 3/4 by portal vein
Almost 1/3 by hepatic artery
Lymph nodes - supradiaphragmatic
Liver biopsy
Right 10th intercostal space in midaxillary line
Hold breath to reduce damage to lung
Hepatomegaly
Rise in central venous pressure
Liver metastasis
Common site of metastasis of GIT, breast cancers

Right of quadrate lobe
Stores liver
Cholecystitis
Inflammation of gallbladder due to blockage
Starts in epigastric, right hypochondriac then to shoulder
Murphy’s sign = sharp pain in RUQ
Cystohepatic trinagle
Liver, cystic duct, common hepatic duct = borders

Gallstones
Cholesterol deposits in cystic duct
Gallbladder referred pain
Referred to right shoulder
Cholecystectomy
Removal of gallbladder
Path of bile
Made in liver - bile canaliculi, ductules, ducts
Goes to gallbladder - hepatic ducts, common hepatic ducts, gallbladder, cystic duct, common bile duct, major duodenal papilla, duodenum
Jaundice
Blockage, bile can’t leave gallbladderP
ancrease
Exocrine & endocrine
Head = in duodenum curve, right
Uncinate process - inferior to head
Neck = hepatic portal vein
Body = part of stomach bed
Tail = close to spleen, spenorenal ligament
