Liver and Gallbladder Flashcards
Synthesis of circulating plasma proteins
Albumins/lipoproteins(VLDLs)/Glycoproteins/Prothrombin and fibrinogen
Storage and conversion of several vitamins and iron
Vit- A/D/K
Degration of drugs and toxins
oxidize or conjugate many water insoluble drugs and toxins
Metabolic pathways
Glycogen storage/Cholesterol metabolism/urea synthesis
Exocrine function
bile production
Endocrine like function
modifies action of hormones released by other organs
- VitD
- Thyroxine
- growth hormone-releasing factor
Portal triad
Portal vein
Hepatic artery
Bile duct
Order from portal vein
Portal vein–> portal venules–> sinusoids–> terminal hepatic venules–> sublobular veins–> hepatic veins–> IVC
Order from Hepatic artery
Hepatic artery–> hepatic arterioles–> sinusoids–> terminal hepatic venules–> sublobular veins–> hepatic veins–> IVC
Kupffer cells
Derived from monocytes and are members of the monuclear phonetic system (MPS)
Destroy aged erythrocytes/digest Hb/destroy bacteria
Perisinusoidal space (space of Disse)
site of exchange btwn blood and liver cells
Ito cells
Hepatic stellate cells–store Vit A
With chronic inflammation or cirrhosis
Ito cells lose storage ability and transform into myofibroblasts–synthesis the collagen that results in liver fibrosis
What increases flow of bile
CCK
Gastrin
Motilin
Parasym stimulation
