Hepatic Tract versus Triad

[Michael Miller]

I updated the liver/pancreas/saliva presentation in the Dropbox with answers to the questions and a few corrections.

Just as a clarification, some sources refer to the hepatic triad as the hepatic tract.  I find this confusing, since from anatomy, we generally think of the hepatic traid as a the macroscopic structure that includes the common hepatic duct, portal vein and hepatic artery.  Hepatic tracts, on the other hand, are the numerous microscopic structures, containing branches from, or tributaries to, the triad, and include (portal) venules, hepatic arterioles and bile ductules.  Yet, keep in mind that some sources use these terms interchangeably.
