?

substances
in the blood roughly constant.

liver lobule:
A)
bile duct
B)
branch of portal vein
C)
branch of hepatic artery
D)
hepatocyte
E)
central vein
F)
sinusoid
G)
canaliculi
7
What is the name of the cells found in the walls of the sinusoid, that break down old
erythrocytes
and remove bacteria?
Kupffer cells
What is the role of the
liver
in storing

Deamination
- removing
amine
group from
amino acid
, forms ammonia(toxic).
Ammonia is converted to less toxic urea.
what happens to the

in the
amino acid
?
