Liver and extrahepatic biliary Flashcards
functions of liver
-Storage, metabolism and release of
nutrients and some vitamins
-Detoxification and elimination of toxins and drugs
anterior to liver
- anterior abdominal wall
- R&L costal margins
- R&L pluera
- ribcage
- xiphoid process
posterior to liver
diaphragm, R kidney and supra renal gland oesophagus, fundus of stomach, gallbladder, sup duodenum
superior to liver
diaphragm
ligaments formed by
a double layer of peritoneum
falciform ligament
liver to the anterior body wall
coronary ligament
liver to the inf surface of the diaphragm
Right triangular ligament
R lobe of the liver to the diaphragm
left triangular ligament
Post part of L lobe to dia.
Ligamentum teres
Fibrous remnant of the L umbilical vein of the fetus
Ligamentum venosum
fibrous remnant of the ductus venosus of the fetal circulation
The posterior surface of the liver is attached to IVC
by hepatic veins and fibrous tissue
liver lobes supplied with blood via
portal vein and hepatic artery.
what is gallbladder and functions ?
Muscular bag for the storage and concentration of bile, delivers bile to small intestine
gall bladder covered by
fibrous layer called hartmans pouch
Recesses around liver
Subphrenic spaces
Morison’s pouch (hepatorenal recess)
Subhepatic space
where is subphrenic space
between the diaphragm and liver, either side of the falciform ligament.
where is subhepatic space
between the inf surface of liver and transverse colon.
where is morisons pouch
between visceral surface of the liver and the right kidney
liver has double blood supply
the hepatic artery
the portal vein
the portal vein…
contains around 40% more
oxygen than blood in the IVC
-75% of the blood in the liver comes
from PV
Liver functional subunits…
The liver lobes are made up of microscopic units called
hepatocytes - Roughly hexagonal in shape
The parenchyma of the liver is
innervated by
hepatic plexus
Glisson’s capsule is innervated
by branches of the
lower intercostal nerves.
