Accessory Organs Flashcards
Largest gland in the body
Liver
Specific regions the liver occupies
Right hypochondruim, across the epigastrium, into left hypochondrium
Connects the stomach and the liver
Lesser Omentum
What ligaments make up the lesser omentum?
heptaogastric and hepatoduodenal ligaments
What does the hepatoduodenal ligament contain?
Common bile duct, proper hepatic artery, hepatic portal vein
Is a reflection of the peritoneum from the liver to the diaphragm
Coronary ligament
What encircles the bare area of the liver, but is considered intraperitoneal?
Coronary and triangluar ligaments
What ligaments split the liver into lobes?
The ligamentum teres hepatic is enclosed by the falciform ligament
What is the falciform ligament continuous with?
Coronary ligament on the superior surface and the lesser omentum at the porta hepatis
Lies between the anterior part of the liver and the diaphragm
Subphrenic recess
Deep recess on the right side between the liver anteriorly and the kidney
Hepatorenal recess aka Morison’s pouch
Where does the fliud draining from the omental bursa flow into?
Morison’s recess
Between the left lobe of the lliver and the diaphragm
Superior recess of omental bursa (lesser sac)
In the middle of the visceral surface of the liver
Porta hepatis
Elongated smooth area that runs from the inferior margin of the liver towards the IVC
Fossa for gallbladder
Posterior aspect of the liver in the bare area contains a space near the midline for a major structure
Groove for IVC
From the inferior border of the liver to the porta hepatis
Fissure for ligamentum teres hepatis
Deep fissure passing from the porta hepatis to the posterior surface of the liver
Fissure for ligamentum venosum
Organs superiorly related to the liver
Base of right lung, pericardium/heart, base of left lung
Anterior relations to the liver
Costal margin, xiphoid process, abdominal wall
Posterior relationships to the liver
Direct contact with the diaphragm, IVC, right suprarenal gland, small portion of the right kidney
Inferior relationships to the liver to the right of the gallbladder
Duodenum, right kidney, right flexure of colon, transverse colon
Inferior relationships to the liver to the left of the gallbladder
Lesser omentum, stomach, esophagus
Lobe between the gallbladder and the fissure of the ligamentum teres anterior to the porta hepatis
Quadrate lobe
Passes to the right between the porta hepatis and the IVC
Caudate process of the caudate lobe
Caudate lobe/process hypertrophy seen with occlusion of hepatic veins
Budd-Chiari syndrome
Inferior projection off of the caudate lobe that may be confused for a pancreatic mass or enlarged lymph node
Papillary process
Functional lobes of the liver
Right, left, caudate
What supplies blood to the right and left lobes?
Separate primary branches of hepatic artery
Blood supply/drainage to the caudate lobe
Both right and left primary branches, drained by it’s own hepatic vein
Provides 75% of the blood to the liver
Portal vein
Provides 25% of blood to the liver
Hepatic arteries
Where is the portal vein formed?
Posterior to neck of the pancrease where the splenic and superior mesenteric ceins join
Path of the splenic vein
Formed in the hilum of the spleen, passes in the splenorenal ligament, passes inferiorly to the splenic artery, posterior to the tail/body of the pancrease
Tributaries to the splenic vein
Short gastric veins, left gastro-omental vein, pancreatic veins, inferior mesenteric vein
