Liver Flashcards
Liver functions (10 total)
-metabolize carbohydrates, proteins, lipids
-storage of glucose as glycogen
-detoxification of waste, drugs, alcohol, chemicals, hormones
-production & secretion of bile
-production of albumin
-regulates heat
-clotting factors
-immune system support using kupffer cells
-filters blood
-fetal hematopoiesis
What vessels supplies blood to the liver
-Hepatic artery supplies 25% of livers blood
-Portal vein supplies 75% of livers blood
Liver ligaments
-Coronary Lig.
-Triangular Lig. (Lt/Rt)
-Falciform Lig.
-Round Lig. (Ligamentum Teres)
-Ligamentum Venosum
-Lesser Omentum
Attaches liver to diaphragm
coronary ligament
Houses Ligamentum Teres; anchors liver to anterior abdominal wall and diaphragm
Falciform Ligament
remnant of obliterated left umbilical vein
Round Ligament
remnant of fetal ductus venosus; an open vessel during fetal development and closes after birth
Ligamentum Venosum
A groove that separates the right and left lobes. It runs obliquely between the gallbladder neck and the right portal vein.
Main Lobar Fissure
Consists of the hepatogastric and hepatoduodenal ligaments
Lesser Omentum
subhepatic space between the right kidney and liver
Morrison’s Pouch
a fibroelastic connective tissue layer that surrounds the liver and the portal triads
glisson capsule
veins that run between segments (INTER), less reflective walls, enlarged toward IVC
Hepatic Veins
veins that run through segments (INTRA), dense borders of fibrofatty tissue (increased echogenicity)
Portal Veins
Labs used for liver diagnosis
ALT & AST, Alkaline phosphatase, bilirubin
aka liver hilum, where triads enter and exit liver
porta hepatis
tongue-like extension of inferior tip of right liver lobe extending beyond Rt. Kidney and reaching down to the iliac crest
Reidel’s Lobe
