what does the central bvein goonto form
ivc
what is the pareenchymla clel of liver
hepatocytes
what are the non parechmyla cell of the liver
liver sinusoid endothelilal cell
hepatic stellate cell
kupffer cells
pit cells
what is the liver sinusoid endothela cell function
cells that lie betwen blood in the sinusoid and hepatic cells maintaining vagla tone and acting as a week barrier
fucntion of hepatic stellate cellcs
storage of vitamen a , and growth factors and repair of liver damgage
kupffer cells role
act as macrophages
pit cells role
regeneration of the liver
what cells are cholangiocytes
billary epitheal cells
what is the role of cholangiocgtes
make up bile duct covering and are not easily degrated
what type of peritnoeum is on the liver
viceral
septa role
to divide liver into smaller subsections
does biule drian towards or waewy form crenal vein
away
where does hepatic blod join liver
half way along hte centre of the porva vein tworeds the cnetre of the hepatic nodule
which way does epatic poart blod go into sinuslid
towrad central vein
hepatocyte role
bile syntheis, nurtirent storage of gycone, fat , vit b12, a, d, e, k, cu, fe
nutrient interconvertson
detoxification
what colour is bilirubin
yellow coulor
what are the componetns of bile
acids, lecithin, cholesterol, bile pigment, toxic metals, bicarbonate
what is the lecintin
the mix of essentio fat of human body

what isht elayres fo the gole balder
mucoa, musclareis, serosa
what is the mucleso folded layers called
rugaue
what ishte role of spincter of odi
control roel of bile and pancrea juie into the duodenum
what hapens to bile when the spincert of oddi is colded
it goes back in to the gal bkadd er and becomes reconcrteaded
what happesn if ther is fat in the duoceum
cck is resaled and goal bldder cojtra na doddi rellex
increased pancre sectioner
how muc does hte gall bladder contectee bile
5 - 20 times
how does the gall balder contare bile
pumps out na using sodium posstaium atp ase pum thus removing water
how is the k replaced outside the cell
a juctoin is in palce, thsu mroe na can be pumped out of the cell
enterophagic cilrue
liver, to bile ductio to duodeni, illeium, hepatic paortv vein, to liver
