Lesson 2D: Liver/GB Flashcards
What are the liver boundaries?
Superior (diaphragm)
Inferior/Visceral (s
Where does the inferior surface of the liver sit?
45 degree angle *
Subphrenic Recess (is a potential space)
Peritoneal space that separates the liver from diaphragm.
Subhepatic Space
Potential space below liver. Inferior to antierior half of the visceral*
Morison’s Pouch (hepatorenal recess)
Potential space in between the liver and right kidney.
Which surface of the liver has multiple depressions on it?
Visceral surface because it is sitting on top of organs
What is another term for inferior surface of the liver?
Visceral
Which portion of the liver is not covered by peritoneum?
Bare area
What surface indentations are on the right side?
Hepatic flexure (colon) Rt. kidney Adrenal gland Duodenum Gallbladder
What surface indentations are on the left side?
Gastric
Esophageal
What surface indentations sits posteriorly?
Groove for IVC
What structures go into liver?
Portal veins (returns nutrient rich blood from spleen, pancreas and intestines)
Hepatic veins (drains into IVC)
Hepatic artery
Hepatic ducts
Ligaments
Fissures (anatomical divisions–help recognize where you are)
*
The liver:
Receives and take up all the nutirents and molecules that are absorpbed from intestines before blood is returned to heart
The portal vein has nutrient-rich and oxygen-poor blood T | F
True
Bile
By product of liver. It gets secreted by liver and **
Bile is stored in the:
Gallbladder
Bile goes into the liver, blood comes out T |F
False
Which portion of the visceral surface of the liver is more inferior?
Anterior right
Describe the location of the IVC in relation to the liver?
Posterior
What two vessels bring blood to the liver?
Portal vein and hepatic artery
Which of the two (portal vein, hepatic artery) has a higher oxygen content?
Hepatic artery
Which side of the visceral surface of the liver does the duodenum make an impression on?
Right
Hepatic duct is inside the liver, bile duct is outside of the liver T F
True
Oxygen rich blood comes from hepatic artery T | F
True
Anatomically, right and left lobes are divided by the:
Falciform ligament (from IVC to GB)
Surgically, the liver would be divided by the main lobar fissure, called:
Cantlie’s Line
What is the free edge of the falciform ligament?
Round ligament
Left lobe is divided into the lateral segment and medial segment T | F
True
Right lobe is divided into anterior and posterior segments T | F
True
Caudate lobe is located where? (caudate is the square shaped small area on liver)
Sits between the IVC and fissure for ligamentum venosum.
Quadrate lobe
It is the more rectangular area it is the more anterior portion of the liver. Sits between GB and fissure of ligamentum venosum (?)(anterior has the same amount of letters as quadrate)
Right lobe is divided into _______ and ________ portions.
Anterior and posterior
Left lobe is divided into _______ and ________ portions.
Medial and lateral
Which lobe of the liver is the smallest?
Caudate lobe
Ligamentum teres is also the:
Round ligament–connects to umbilicus
Caudate lobe is retroperitoneal T | F
False (even though IVC is retropertioneal)
What marks the surgical/functional division between the right and left lobes of the liver on the anterior surface?
Cantlie’s line
Anatomical divison?
Falciform ligament
On the visceral surface of the liver, what separates the posterior caudate lobe from the more anterior quadrate lobe?
Porta hepatis
What structures make up the “cross bar of the H”?
Porta hepatis
Which liver lobe is more anterior?
Quadrate lobe
Gallbladder is:
A little resovoir that holds bile. Only attached to the liver by the neck of the GB, everything else is free moving.
Gallbladder is divided into:
Neck (connected to cystic duct)
Body
Fundus
When you eat a fatty meal, the hormonal feedback system controls the flow of bile from the GB into the duodenum. T | F
True
Describe the fundus:
Most inferior and anterior portion, usually the bile will be stored here (because of gravity).
What is the fundus in contact with?
Duodenum, transverse colon and anterior abdominal wall.
Describe the body:
Extends upwards from fundus and is in direct contact (but not attached to) the visceral part of the liver. Largerst part.
Hartmann’s Pouch (the infindibulum):
Common for gallstones to be lodged. Weaker area of the wall, a mucousal fold or slight ***
What surface of the liver is the GB located on?
Anterior visceral
What liver landmark is it located within?
Cantlie’s line (within the main lobar fissure)
Where is Hartmann’s pouch located?
Neck of GB
What structure does bile flow through within the parenchyma?
Hepatic ducts
What part of the GB protrudes from the inferior aspect of the liver?
Fundus
What portion of the gallbladder is attached to the liver?
Neck
How many segments of the liver are there?
8–because each segment of the liver has its own blood supply.
What 2 veins divide the liver?
Portal and hepatic
In the ceterne of each segment there is a branch of:
Portal triad–hepatic artery, portal vein, and bile duct.
In the center of each segment, there is a branch of:
Portal triad–hepatic artery, portal vein, and bile duct.
In the otuer portion of the segment is the
Portal vein
What are the segments? (Start at back of liver and go clockwise)
Seg1-caudate lobe Seg2/3-lateral left lobe Seg4-medial left lobe divided into 4a(sup) and 4b(inf) Seg5/8-anterior right lobe Seg6/7-posterior right lobe
Left portal vein is more _______: (sup or inf)
Superior
You are very superior/inferior when you see the IVC:
Superior
You are very superior/inferior when you see the IVC:
Superior
What divides the liver into superior and inferior portions?
Portal Veins
If the portal vein is viewed on a (transverse) scan, you are not sure what segment you are on because you are on the division. T | F
True
