Liver Gallbladder And Pancreas Flashcards
The largest and heaviest solid organ is
The liver
Which lobe of the liver is the largest
The right lobe
What is the name of the connective tissue capsule that surrounds the lobes in the liver
Glisson capsule
What lies on the visceral surface of the liver
Porta hepatitis which is gateway for hepatic ducts, portal vein, hepatic artery, lymphatics and nerves
The blank plays a central role in metabolism of carbohydrates, proteins and fats, modification; modification of exogenous substances (alcohol, drugs,); and formation of exocrine glands
The liver (Exam Q)
80% of liver tissue is made up of. The remaining 20% is
Parenchyma, stroma
What composes the portal triads
Hepatic artery, portal vein, and bile duct
What is a unique feature of the hepatic lobule in the liver
It has dual blood supply
The dual blood supply composes
Portal veins brining nutrient rich blood GI system
Hepatic arteries bring the rest
Portal veins and hepatic arteries of the hepatic lobule in the liver empty into what
Hepatic sinusoids
the components of the portal triad are accompanied by
Small lymphatics
Bile ductule is lined by
Simple cuboidal to simple columnar
Billary passage starts with
Bile canaliculi between hepatocytes
Canals of herig
Are when canaliculi approach the periphery of each lobule and drain by small ducts known as the canals of herig, lined by simple cuboidal epi
What are the spaces that separate endothelial lining that separate sinusoid and hepatocytes
Perisinusoidal space or space of disee
What do the perisinusoidal spaces/ spaces of disse allow for
Plasma to flow and permit exchange of substance
the oval diamond shaped area of the parenchyma is called
The liver acinus
The liver has two types of axis
Its hepatocytes has 3 what
Short axis runs along the border of the 2 lobules
Long axis is an imaginary line between two central veins
3 concentric zones
The liver acinus has 3 zones name them and their important structure
Zone 1 is the most central and has most oxygen
Zone 2 intermediate zone
Zone 3 furthest from the portal venue and hepatic arteriole and is the least oxygenated; and its the first to show ischemic necrosis and fat accumulation if metabolism is altered
What are the body’s largest fixed macrophage population
Kupffer cells
The luminal surface of the hepatic billary ducts system has what
Microvilli with occasional cilia
What are the 3 layers of the gallbladder
The mucosa, muscularis propria, and the adventia/serosa
What layer is missing from the gallbladder
The submucosa (EXAM)
What type of cells make up the mucosa of the gallbladder
Simple columnar epi
