Anatom3DCaudate & quadrate lobes
Lobus caudatus et lobus quadratus · Ocasatý a čtyřhranný lalok
Digestive system
Looks like
Two small lobes on the underside of the liver: the caudate at the back by the vena cava and the quadrate in front by the gallbladder.
What it does
Do the same work as the rest of the liver; the caudate drains straight into the vena cava.
Keeping it well
When the main hepatic veins clot (Budd–Chiari syndrome), the caudate lobe is spared and enlarges, a sign seen on scans.
