Q

What are the components of the hilum (porta hepatis) of the liver?

A

Portal Triad:

  • Portal vein (brings blood to liver)
  • Hepatic Artery Proper (O2 to liver)

Q

Describe the general course of the coronary ligaments on the L and R sides of the liver

A
  • Coronary ligaments are peritoneal reflections that straddle the center of the liver.
  • The superior part of the ligament reflect back to make the inferior coronary ligament
  • The corner formed by reflection of this tissue forms the R and L triangular ligaments
18
Q

What provides a route for the spread of cancer from the liver to lungs or visa versa?

A

Hepatic Bare Area
- Lymphatic vessels pass between the abdominal cavity and thorax and lie on this area that is not covered by visceral peritoneum.

19
Q

What area is located between the superior and inferior coronary ligaments on the right side?

A

Hepatic Bare Area

20
Q

The L and R inferior coronary ligament meet to become the ___________ that is a part of the ___________.

A

hepatogastric ligament
Lesser omentum

Note: the attachment point of the hepatogastric ligament is the fissure of the ligamentum venosum

21
Q

Describe the structures contributing to the formation of the bile duct before it enters the duodenum.

A

R and L hepatic ducts join to form the common hepatic duct which is joined by the cystic duct to form the common bile duct which is joined by the pancreatic duct just before entering the duodenum

22
Q

What structures is the gallbladder in contact with?

A

Superiorly: Liver
Inferiorly: Transverse Colon
Inferior to neck of GB and medially: Duodenum
Laterally: Abdominal Wall

23
Q

What are the 3 branches of the celiac artery?

A
  1. Left Gastric
  2. Splenic
  3. Common Hepatic
24
Q

Describe the branching of the left gastric artery.

A

gives off esophageal branch

25
Q

Describe the branching of the Splenic artery.

A

a. Branches to Pancreas
b. to hilium of spleen
c. short gastric
d. Left gastro-epiploic

26
Q

Describe the branching of the Common Hepatic Artery.

A
  1. Proper Hepatic
    - R and L hepatic
    - Cystic
    - right gastric
  2. gastroduodenal
    - gastro-epiploic
    - superior pancreatico-duodenals
27
Q

What two arteries anastomose on the lesser curvature of the stomach?

A

R and L gastric

28
Q

What two arteries anastomose on the greater curvature of the stomach?

A

R and L gastroepiploic

29
Q

T or F: the Common hepatic a. gives off branches that supply bother the superior and inferior aspects of the stomach.

A

True
Superior - R. gastric
Inferior - gastro-epiploic

30
Q

What veins join to form the hepatic portal vein?

A

Splenic vein and SMV

31
Q

Describe the attachment of the lesser omentum to the liver.

A

J shaped attachment formed by the ligament attaching at the porta hepatis and fissure for ligamentum venosum

32
Q

T or F: the pancreas is in contact with the spleen.

A

True - the tail of the pancreas lays against the hilum of the spleen.

33
Q

What two mesenteries meet at the hilum of the spleen?

A

Splenorenal mesentery and gastrosplenic mesentery

34
Q

A needle is inserted at the top of the 9th rib in the left lung but instead of stopping at the pleural recess it pierces the diaphragm as well as an underlying structure. What is this structure?

A

Spleen

35
Q

What part of the liver is in association with the lesser sac?

A

Caudate lobe

36
Q

What part of the liver is associated with the epiploic foramen?

A
  • Skinny tail of caudate lobe that runs behind the IVC

- this forms the roof of the epiploic foramen

37
Q

What accounts for 100% of the venous drainage from the liver?

A
  • Hepatic veins draining into the IVC
38
Q

T or F: the Fundus of the gallbladder is in the transpyloric plane

A

True

39
Q

What structures allows for communication of the Bare area of the liver with the diaphragm and lungs?

A

Lymphatics

40
Q

What type of people typically need their gallbladder taken out?

A
  • Females
  • Fat
  • Forty
  • Fair
  • Flatulent
41
Q

What part of the liver gets blood from the splenic and inferior mesenteric veins?

A

Left Lobe

42
Q

What delivers most of the blood to the liver?

A

Hepatic Portal vein (delivers ~80% of blood)
