Bloodsupply Liver Flashcards
ARRIVING vessels to the LIVER
A. HEPATICA (ex. A.coelica) - R.Dexter Lat/Med (Right lat/med lobes) - R. Sinistrum (To the left side) -r.sinistri medialis (L medial + Lobus QUADRATUS) -r.sinistri lateralis -> Left lateral lobe - A.Interlobularis (liver trias) = NUTRITIONAL
V. PORTA
(ex. V.lienalis, V.mesenterica cran et caud)
- V Interlobularis (liver trias)= FUNCTIONAL
LEAVING vessels FROM the LIVER
Central veins - Sublobular veins - Hepatic veins - V. Cava caudalis
- Central veins collect blood from the LIVER LOBULES.
And then they form the: - Sublobular veins
Which fuse into: - Heparic veins
And then Hepatic veins enter into - VENA CAVA CAUDALIS
Vessels ARRIVING LIVER
- A. Hepatica
Ex Coeliaca
(Branch of the Coeliac artery)
A.Hepatica gives branches towards each lobes:
- Ramus dexter lateralis and medialis
(Towards the right lateral and medial lobes) - Ramus sinister (to the left side)
Which will give:
I: Ramus sinistri mediales
(to the left medial Lobe and Lobus QUADRATUS)
II: Ramus sinistri laterales
(To the left lateral Lobe)
And then these vessels further devide into:
- Arteria Interlobularis (is a part of the liver trias) and they give the NUTRITIONAL supply of the liver!
Vessels ARRIVING the LIVER
- V.PORTAE
2nd vessel arriving the liver!
Ex V.lienalis, V. Mesenterica cran, V. Mesenterica Caud
Collecting the blood from the:
V. lienalis
V. Mesenterica cran
V. Mesenterica caud
And then it branches into:
V. Interlobularis (part of liver trias)
Gives the functional blood
Vessels of the Liver
