Hepatic Vasculature Flashcards
3 components of hepatic vasculature
HV, HA, portal venous system
hepatic veins (function, course, how many, location, join IVC where)
drain blood from liver into IVC
course inf/ant to sup/post
3 major
located in intersegmental fissures
join IVC just inf to diaphragm
hepatic artery (supplies, branches from)
supplies 20-30% of blood to liver
R branch of CA
branches of hepatic artery
common hepatic
hepatic artery proper
common hepatic artery (starts, courses)
from origin of CA to junction of GDA
courses towards r side
hepatic artery proper (starts, courses, forms)
from GDA to bifrucation of R/L hepatic arteries
travels sup and R lat toward liver
travels into porta hepatis forming part of portal triad
porta hepatis (what, AKA)
entrance/exit into liver
AKA hilum of liver
portal triad
consist of HA, PV, and BD
at porta hepatis: HA, MPV, CBD
HAP is _____ to CBD and _____ to MPV at portal triad
medial
anterior
RHA supplies _____ LHA supplies ____
R lobe/branches to caudate
mainly L lobe
portal venous system (function, supplies how much blood)
carries nutrient-rich blood from the GI tract
supplies 70-80 % of blood to liver
does the portal venous system connect directly with IVC
no
