How many lobes are in the liver
4 lobes
What is the Couinaud classification
The functional anatomy breaks the liver into 9 sections
What is the porta hepatis
Where the hepatic artery, portal vein, left/right hepatic duct enter
What covers the outside of the liver
Glisson capsule
*contains neuromuscular supply
What part of the liver is not covered by peritoneum
Posteriorly
What separated the right and left and right lobes of the liver
Falciform ligament
*attaches to anterior abdominal wall
What is the ligamentum teres (Round ligament) of the liver
Extension off the falciform ligament that attaches to umbilicus
Remnant of the umbilical vein
What attaches the liver to the diaphragm
Coronary ligament
How much of the CO goes to the liver
25%
How much venous blood is in the liver
1000-1200mL/min
How much arterial blood is in the liver
400-500 mL/min
What is the functional unit of the liver
liver lobule
What type of cells make up the liver lobule
hepatocytes
*functional unit for protein production
What are sinusoids in the liver
capillaries between hepatocytes that receive both arterial and venous blood
Where do sinusoids drain
central vein which then drains into hepatic vein -> IVC
What is the hepatic triad
Bile ductule
branch of portal vein
branch of hepatic artery
What are Kupffer cells
phagocytes
*#1 nom nom cells in the body but stay in the liver
Where are kupffer cells found
in the sinusoids of the liver
What makes up bile
bile salts (acids)
cholesterol
bilirubin
electrolytes
water
What is the ampulla of vater
Where the gallbladder connects to the duodenum and the area just before the sphincter of oddi
Where do bile salts get reabsorbed
terminal ileum and then returned to portal circulation
What is heme converted to before entering plasma
Bilirubin
What type of bilirubin is lipid soluble
unconjugated (bound to albumin)
What happens with conjugated bilirubin
