What is the largest gland in the body?
liver
What are the function of the liver?
bile secretion
metabolism of proteins, fats, and carbohydrates
storage of glycogen, vitamins, iron
detoxification
What are the two surfaces of the liver?
Diaphragmatic and visceral surface
What is the diaphragmatic surface?
superior and convex
What is the visceral surface?
inferior and concave
What is the porta hepatis?
hilum of the liver
What does the porta hepatis contain?
common hepatic duct
hepatic artery proper
portal vein
What is not in the porta hepatis?
inferior vena cava
Where does the right lobe of liver set?
gall bladder lies in fossa on its visceral surface
inferior vena cava lies posterior to gall bladder
Where does the quadrate lobe of liver set?
between right and left lobes
anterior to porta hepatis
gall bladder is immediately to right of it
Where does the caudate lobe of liver set?
between right and left lobes
posterior to porta hepatis
Where does the left lobe of liver set?
left of the falciform ligament
smaller than right lobe
Where do hepatic segments 1-4 set?
in left functional half
Where do hepatic segments 5-8 set?
right functional half
What structures distribute to the right and left functional halves of liver?
hepatic artery
portal vein
common hepatic duct
hepatic vein
What is the bare area of the liver?
where the liver is not covered by visceral peritoneum
Where is the bare area located on the liver?
diaphragmatic surface
What structure lies in the bare area of the liver?
inferior vena cava
What does the falciform ligament of the liver do?
connects liver to diaphragm and anterior abdominal wall
What does the coronary ligament of liver do?
forms borders of bare area, and reflects onto diaphragm
What forms the coronary ligament?
falciform ligament splits once it passes posteriorly on diaphragmatic surface
Where is the right and left triangular ligament formed?
at junction of superior and inferior layers of coronary ligament on each side
What does the ligamentum teres form?
free edge of falciform ligament
What is the ligamentum teres made of?
is remnant of obliterated umbilical vein
Where does the ligamentum venosum lie?
between left and caudate lobes
What is the ligamentum venosum made of?
remnant of ductus venosus
What does the ligament of inferior vena cava cover?
covers inferior vena cava within bare area of liver
What does the fissures of the liver make?
H
Where is the fissure for the ligamentum teres?
left lobe and quadrate lobe
Where is the fissure for the ligamentum venosum?
between left lobe and caudate lobe
Where is the fossa for the gallbladder?
right lobe and quadrate lobe
Where is the fissure for the inferior vena cava?
between right lobe and caudate lobe
What forms the crossbar of the H
porta hepatis
What is the blood supply to the liver?
portal vein 80% and hepatic artery 20%
What is the innervation of the liver?
autonomic and pain fibers are from hepatic plexus
