3 - umbilical cord
Once the hepatocytes have created the bile, it then makes it way to be stored in the gall bladder. Organise the order this process takes place:
1 - common hepatic duct merges with cystic duct
2 - bile canaliculi join to form left and right hepatic ducts
3 - cystic duct merges with common bile duct
4 - left and right hepatic ducts converge into common hepatic duct
2 - bile canaliculi join to form left and right hepatic ducts
4 - left and right hepatic ducts converge into common hepatic duct
1 - common hepatic duct merges with cystic duct
3 - cystic duct merges with common bile duct
Is the majority of blood in the liver from the arterial or venous supply?
- venous
- arterial = 25%
- venous = 75%
The liver is located in the foregut. What is the main artery supplying the foregut?
1 - superior mesenteric artery
2 - inferior mesenteric artery
3 - coeliac artery
4 - abdominal artery

4 - 60%
The liver contains hepatic lobules that resemble a hexagon. On the peripheries of this hexagon are triads. Which of the following is NOT contained within these triads?
1 - arteriole
2 - lymph nodes
3 - venule
4 - bile duct
2 - lymph nodes
- lymphatic and nerves are present here as well
The triads that are on the peripheries of the hepatic lobules are triads containing arterioles, venules and bile ducts. What is at the centre of the hexagon shaped hepatic lobules?
1 - portal vein
2 - supervior vena cava
3 - porta hepatis
4 - central vein
4 - central vein
- central vein drains into the portal vein that subsequently drains into the superior vena cava
