Liver and gallbladder

Two main cell types in liver

Hepatocytes (liver cells), macrophages (stellate macrophages or kupffer cells)

Functions of the liver

Plasma proteins, bile formation and secretion, metabolism of lipid soluble drugs and steriods, lipoprotein synthesis and secretion, carb metabolism, urea formation

How to identify liver

Dense, collagenous CT capsule, hepatic lobules, and veins

Blood goes through what in the liver

Portal vein, hepatic artery, sinusoids, hepatic sinusoids, bile duct

What does portal vein do

Brings newly absorbed substances from intestines to liver

What do sinusoids do

filter substance through hepatocytes and macrophages

What does hepatic artery do

Brings blood to liver cells, branched off from abdominal aorta

What are hepatic sinusoids

Where portal vein and hepatic artery mix

What is central veins

Where blood from portal vein and hepatic artery collect

Where does blood drain out of liver

hepatic vein

What makes up portal triad

portal vein, hepatic artery, bile duct

What is perisinusoidal space

space between hepatocytes and endothelial cells

What is bile made of

water, bile salts, cholesterol and phospholipids, pigments, electroytes

How is bile made

produced by hepatocytes, collected in bile cancliculi encircling hepatocyte

What is common hepatic duct

drains bile from liver

What is cystic duct

connects common hepatic duct to gall bladder, carries bile in and out

What is common bile duct

fused common hepatic duct and cystic duct, empties bile into dueodenum

What does gallbladder do

stores, concentrates, acidifies, delivers bile to duodenum

Histological appearances of gallbladder

no lamina muscularis mucosae, simple columnar,has serosa and adventitia
