which of the following is CORRECT:

75% of blood to the liver is supplied by the portal vein

middle hepatic joins the right hepatic vein before meeting the IVC

Common hepatic artery gives rise to the gastro duodenal artery

Portal venous system has no valves

bhavu question given is this only.....

i chkd.....

if its all except what u think is the answer?

bhavu · Credits: 9481 My Scrapbook

actually i think in bdc or physio any book it is written that 2/3rd of blood supply ofliver is by portal vein.

and all three right left and middle hepatic vein forms confluence before entering in to ivc.

so as such all option seems to be correct but exat percentage is 66% not 75% you can take like that

or you can tell that in infancy portal vein has valve and some persist as a rudimentary valves.

so these are facts frame you answer according to you veiws

actually answer given is 2).......
thats the only correct the buk says..then if we consider 66% to be correct but can we ignore 3) ?

the ans is 3)common hepatic art. gives rise to to gastro-duodenal art.

Reason:
1) 60-66% blood is supplied by hepatic v.
2) All the 3 veins join the ICV independently
4) portal system has valves

Correct me if I m Wrong

max share of portal vein in upto 70%
rest all options are 100% correct
so the only option is a printing mistake in the question
