What is the are the two types of cells of the intercalated duct in the pancreas? and what are their function?
Centroacinar cells- project into acini
Ductal cells- secrete water and bicarbonate
Where are Acinar cells located and what shape are they?
in the Acini of the pancreas
pyramidal
Where are zymogen granuels found and what do they have?
in the Acini of the pancreas
has inactive digestive enzymes
What is Glisson’s capsule of the liver?
connective tissue capsule
What does the portal canal contain?
Portal triad

Perioportal space
What is the perioportal space
space between hepatocytes and portal canal
What type of epithelium does the bile duct contain
simple cuboidal epithelium
what does the portal traid consist of
portal vein
hepatic artery
bile duct
What is at the corners of the hepatic lobule?
portal canal
What is in the center of the hepatic lobule?
What is at the corners of the hepatic lobule?
What is the shape of the hepatic lobule?
Central vein
portal canal
hexagonal
What does the hepatic lobule trace?
blood flow through the liver
How does blood supply the liver?
dual supply
portal vein and hepatic artery
What is the path of the blood flow through the liver
portal vein and hepatic artery anastomose to form sinusoids (hepatocytes process blood here)
Flows into central vein
flows into hepatic veins
Flows into IVC
What is in the short axis of the hepatic acinus?
What is at the long axis of the hepatic acinus?
What is the shape of the hepatic acinus?
opposing portal canals
opposing central veins
Quadrangular

What is the shape of the portal lobule?
portal canal
central vein
triangular
What does the hepatic acinus describe?
blood perfusion and metabolic activity
What does the portal lobule trace?
production of bile
Describe zone 1 and zone 3 of the hepatic acinus to me
zone 1= high O2 nutrients toxins
Zone 3= high co2 metabolic waste
