What layer of peritoneum does the liver form within?

- a double layer of peritoneum called the ventral mesogastrium


What separates the right and left anatomical lobes of the liver?

- the falciform ligament


What are the two surfaces of the liver?

- the diaphragmatic surface and the visceral/inferior surface


Which two lobes are found on the visceral/inferior surface of the liver?

- the quadrate lobe and the caudate lobe


The hilum of the liver is found on which surface? What is it also known as? What does it contain?

- found on the visceral/inferior surface
- also known as the porta hepatis
- contains the hepatic ducts, portal vein, and hepatic artery proper


What is the thicker cord of the falciform ligament called? What is it the remnant of?

- the ligamentum teres, which is the obliterated umbilical vein


The quadrate lobe is bordered by ________ and ________. The caudate lobe is bordered by ________ and ________.

- quadrate: gall bladder and fissure for ligamentum teres
- caudate: IVC and fissure for ligamentum venosum (remnant of ductus venosum)


What is the double layer of peritoneum between the liver and the stomach?

- the lesser omentum


The hepatorenal recess is also known as:

- Morrison's pouch (between the liver and right kidney)
- (fluid can accumulate in here during surgery)


What are the three main areas of portosystemic anastomoses/varice formation?

- lower esophagus: esophageal varices can bleed profusely
- rectum and anal canal: hemorrhoids
- paraumbilical veins: caput medusae


The _________ and _________ form the the common hepatic duct, while the _________ and __________ form the common bile duct.

- right hepatic duct + left hepatic duct --> common hepatic duct
- common hepatic duct + cystic duct --> common bile duct


The common bile duct joins with the main pancreatic duct to form a dilatation known as the ____________, which empties in the ___ part of the duodenum via the _______ duodenal papilla.

- dilatation of the two ducts = hepatopancreatic ampulla (AKA ampulla of Vater)
- bile duct empties into the 2nd part of the duodenum via the major duodenal papilla


The minor duodenal papilla lies ______ the major duodenal papilla and drains the _____________.

- minor is ABOVE the major
- drains the accessory pancreatic duct


The sphincter of Oddi is the sphincter around the:

- hepatopancreatic ampulla (ampulla of Vater)
- (in addition: the common bile duct has a sphincter of the bile duct; the pancreatic duct has a sphincter of the pancreatic duct; when these two merge into the ampulla of Vater, you now have the sphincter of Oddi surrounding them)


Which artery supplies the gallbladder? Where does it branch from?

- the cystic artery, which is usually a branch of the right hepatic artery


The cystohepatic triangle is more commonly known as the __________. What is it made up of?

- known as the triangle of Calot
- formed by the cystic duct, the inferior/visceral surface of the liver, and the common hepatic duct


Name the parts of the pancreas. What "passes through" the pancreas?

- the uncinate process, the head, the neck, the body, and the tail
- the superior mesenteric artery and vein "pass through" the pancreas (they pass behind the neck/body and then in front of the uncinate process)


Which major arterial branches arise from the splenic artery near the hilum of the spleen? Which organs do they supply?

- the short gastric arterial branches supply the fundus of the stomach
- the left gastroepiploic artery supplies the greater curve of the stomach
