Q

the proper hepatic artery has 2 branches off of it… what are they?

A

right hepatic artery

left hepatic artery

16
Q

what are the 3 branches off of the gastroduodenal branch?

A

right gastroepiploic artery
posterior superior pancreaticoduodenal a.
anterior superior pancreaticoduodenal a.

17
Q

what is the main blood supply to the stomach?

A 
left gastric artery
right gastric artery
left gastroepiploic artery
right gastroepiploic artery
short gastric arteries
18
Q

where does all the blood supply from the stomach drain?

A

directly or indirectly into the Portal vein

19
Q

what does the porta hepatitis contain?

A 
right and left hepatic ducts
branches of proper hepatic artery
branches of portal vein
autonomic nerves
hepatic lymph nodes + vessels
20
Q

what forms the right sagittal fissure of the liver (right limb of the ‘h’)?

A

groove for gallbladder and groove for IVC

21
Q

what forms the left sagittal fissure (left limb of ‘h’)?

A

fissure for round ligament of liver and fissure for ligamentum venosum

22
Q

what does the ductus venosus do?

A

allows blood to bypass liver and go straight to IVC

23
Q

what does the ductus venosus become after birth?

A

ligamentum venosum

24
Q

what are the 4 lobes of the liver?

A

quadrate lobe
caudate lobe
right lobe
left lobe

25
Q

where is the quadrate lobe of the liver?

A

anterior to the porta hepatitis

26
Q

where is the caudate lobe of the liver?

A

posterior to the porta hepatitis

27
Q

where is the round ligament of the liver?

A

the inferior free margin of the falciform ligament

28
Q

where is the bare area of the liver?

A

on the posterior side

between the superior and inferior layer of the coronary ligament

29
Q

where are the right and left triangular ligaments?

A

the right and left ends of the coronary ligament

30
Q

what is the blood flow through the liver?

A

liver receives blood from the proper hepatic artery and portal vein
this artery and vein divide into progressively smaller branches
they mix blood in liver capillaries
blood is collected by hepatic veins
the veins get bigger until 3 main ones are formed (right intermediate and left)
the hepatic veins drain into IVC

31
Q

what is the flow of bile out of the liver?

A

right / left hepatic ducts
common hepatic duct
common hepatic + cystic = common bile duct
common bile duct + pancreatic duct= ampulla of Vater
opens into duodenum through major duodenal papilla surrounded by sphincter known as sphrincter of Oddi

32
Q

where in the body anatomically is the gallbladder?

A

9th costal cartilage

33
Q

what makes up the cystohepatic triangle of Calot

A

cystic duct
common hepatic duct
inferior surface of liver

34
Q

where in the body is the long axis of the spleen?

A

the 10th rib

35
Q

what is the blood supply of the speen?

A

splenic artery and splenic vein
