AB The  portal  vein  carries  approximately  1.5  L/min  of  blood  from  the  splanchnic  circulation  to  the  liver.  Unlike  most  veins  in  the  body,  the  portal  vein  lacks  valves.  It  constitutes  around  80%  of  blood  supply  to  the  liver,  with  portal  venous  flow  estimated  to  be  around  2  cm/sec.  The  normal  pressure  of  the  portal  vein  is  around  5  mm  Hg,  and  pressure  greater  than  10  mm  Hg  results  in  the  development  of  portosystemic  shunts  such  as  gastroesophageal  varices.
