Er zijn 2 aanvoerende vaten, de poortader en de leverslagader. Er is 1 afvoerend vat, de leverader.
Poortader; loopt vanaf de dunne darm naar de lever. Het is zuurstof arm (al verbruikt in de dunne
darm). Het is wel voedingsstofrijk (voedingsstoffen die in het spijsverteringskanaal verteerd zijn
worden via de poortader naar de lever gebracht)
Leverslagader; zuurstofrijk (komt rechtstreeks van hart en longen) en voedingsstof arm
Leverader; zuurstofarm, voedingsstofrijk en vol met afvalstoffen. Dat word uitgescheiden via de gal-
darmen-ontlasting of bloed-nieren-urine.
Levercel
Bloed gaat vanaf de leverslagader (arterie
hepatica) en poortader naar het centrum
(centrale ader).
Gal ontstaat in de levercellen, dit gaat in
tegengestelde richting naar de galgang.
