Anatomy of Liver, Gallbladder and Pancreas Flashcards
Name the 3 accessory digestive organs in the abdominal cavity that help in the chemical breakdown of food?
- liver 2. gall bladder 3. pancreas
Describe characteristics of the liver?
- reddish brown - great vascularity 2. stores glygogen + secretes bile 3. largest internal organ - 1.5 kg in adults
Where is the liver located?
beneath the diaphragm in the right upper quadrant - right hypochindriac + epigastric
Name the surfaces of the liver?
- diaphragmatic surface 2. visceral surface 3. bare area
Describe the diaphragmatic surface?
- diaphragm is anterior + superior + some posterior 2. smooth + dome-shaped
What seperates the diaphragmatic surface from the diaphragm?
left + right subphrenic recesses
What seperates the subphrenic recesses into left and right?
falciform ligament
Describe the bare area of liver?
- posterior to diaphragm
2. demarcated by reflections of upper & lower layers of coronary ligament
Describe the visceral surface?
covered by peritoneum except porta hepatis
What are the relations of the visceral surface?
- stomach + lesser omentum
- duodenum + right colic flexure
- gall bladder, right kidney + suprarenal gland
Describe the hepatorenal recess?
between right kidney and right lobe of liver
Describe the lobes of the liver?
has functionally independent right and left parts that are approximately equal in size
Each part of the liver has its own?
- blood supply - hepatic artery + portal vein
2. venous + biliary drainage
What seperates the 2 lobes on the visceral surface?
gall bladder + IVC fossae
The caudate and quadrate lobes function as part of which lobe?
left lobe
Why are the quadrate and caudate lobes part of the left lobe?
they are supplied by left hepatic artery, left branch of portal vein & deliver bile to left hepatic duct
The caudate and quadrate lobes are anatomically part of which lobe?
right lobe
What are the lobes of the liver?
- right 2. left 3. caudate 4. quadrate
Where is the caudate lobe?
between IVC and fissure for ligamentum venosum (ductus venosus)
Where is the quadrate lobe?
between the gall bladder fossa and ligamentum teres (umbilical vein)
Function of the falciform ligament?
- seperates right from left lobe anteriorly 2. attaches liver to anterior abdominal wall + diaphragm
Describe the ligamentum teres?
- continuous with falciform ligament to umbilicus 2. remnant of umbilical vein of fetus
What is the porta hepatis?
fissure on visceral surface between caudate and quadrate lobes
The porta hepatis gives passage to?
- hepatic artery 2. portal vein 3. hepatic ducts 4. lymphatics 5. nerves
What is the epiploic foramen?
opening where the lesser and greater sac communicate
What are the relations of the epiploic foramen?
- anterior - hepatic artery, portal vein + bile duct 2. posterior - IVC
