The Liver Flashcards
Main function of the liver
Biosyntheic chemical factory, synthesizing large complex molecules (can just say synthesizing large complex modules)
What is the functioning of the liver dependent upon
- Hepatocytes
- Vasculature
- Bile drainage system
Which cell is the main functional cell of the liver
Hepatocyte
Describe the structure of the hepatocyte (include organelles)
- Polygonal
- Has many nuclei
- Multiple mitochondria
- Multiple Golgi apparatus
- Multiple rER and sER
- Lysosomes
Name the 3 surfaces of the hepatocyte
- Intercellular (hepatocyte to hepatocyte)
- Sinusoidal (hepatocyte to sinusoid)
- Canalicular (hepatocyte to bile caniculi)
Name the two sources of blood for the vasculature
- Hepatic artery
- Hepatic portal vein
Which blood source of the vasculature contains blood rich in nutrients for the liver?
- Hepatic portal vein
What do the hepatocytes produce
Bile
What type of duct does the bile leave as in the liver
- common hepatic duct
What type of duct does the bile leave as from the gall bladder
- Commin bile duct
Describe the layer of the gall bladder
- Inner epithelial layer
- Lamina propia
- Muscular layer
- Outer fibrous layer
What makes up 70-80% of the liver
Hepatocyte
What is the structural (shape) difference between the lobule and the acini
Lobule : hexagonal
Acini: diamond
Difference between the lobule and acinus
Lobule:
- Has central vein and portal tracts at the periphery
Acinus:
- Has portal tract at the centre and central vein at the periphery
Name two diseases from liver complications
- Cirrhosis
-Tumors - Gall stones
- Jaundice
