Where is the caudate lobe of the liver?
posterior and superior, central part of the liver, just above the gall bladder
Where is the quadrate lobe of the liver
Between the gall bladder and the common bile duct.
What vessels are associated with the caudate lobe?
left and right hepatic arteries
What Organs are in the foregut, midgut and hindegut?
ED and JT are DRs (Esophagus to beginning of Duodenum; Jejunum (and latter part of duodenum) to Transverse colon; Descending colon to rectum)
