Hepatobiliary system Flashcards
What are the two primary lobes of the liver?
Right and left
Which folds connect the liver to the abdominal wall and diaphragm?
Pertioneal folds (ligaments)
What vessel delivers the majority of blood to the liver?
Hepatic portal veins
Which vessels deliver blood to the liver?
Hepatic portal veins
Hepatic artery
What % of blood flow arises from the hepatic artery into the liver?
25%
What is the hepatic artery?
Delivers oxygenated blood from the heart to the liver
What is the hepatic portal vein?
Delivers partially deoxygenated blood containing nutrients and toxins absorbed from the small intestine, pancreas, gall bladder and spleen to the liver
What is the main outflow of the liver?
There are 3 hepatic veins (right, middle and left), these drain into the inferior vena cava
The right and left hepatic duct converge to form which duct?
The common hepatic duct
Where do the right and left hepatic ducts converge?
The hilum
Which duct does the common hepatic duct converge with to form the common bile duct?
The cystic duct
What is the primary function for the common bile duct?
Carry bile to the duodenum of the small intestine. Bile produced by the liver is pushed back up the cystic duct y peristalsis to arrive in the gallbladder for storage.
What are the three main hepatic veins?
Right hepatic vein
Middle hepatic vein
Left hepatic vein
What is the middle hepatic vein, and its role in liver anatomy?
Obliquely runs from the inferior vena cava to the gallbladder fossa. Separates the anterior and medial segments of the right hepatic lobe.
What is the right hepatic vein and its anatomical divisions?
Divides anterior and posterior segments of the right hepatic lobe
What is the left hepatic vein and its anatomical divisions?
Left hepatic vein separates the medial and lateral segments of the left hepatic lobe
Where do the 3 hepatic veins drain into?
Inferior vena cava
Which ligament separates the lateral and medial segments?
Ligamentum teres
In which direction are segments II - VII numbered?
Clockwise fashion
What are the three main components of the liver?
Hepatocytes
Bile canaliculi
Hepatic sinusoids
What are the main hepatic cells?
Hepatocytes
What term is used to describe plates of hepatocytes?
Hepatic laminae
What are hepatic laminae?
Plates of hepatocytes.Hepatic laminae radiate outward from the portal vein in each hepatic lobule.
What is in the central of the hepatic lobule?
Central vein
