Intrasegmental portal triad vessels are embedded inside the liver parenchyma, traveling within portal tracts from the porta hepatis toward the center of each hepatic segment. In practice, the portal vein, hepatic artery, and bile duct march through the liver tissue, so within a given segment you find these vessels heading inward toward the segment’s central area rather than lying on the surface or at the outer edges. They don’t enter the liver from the gallbladder bed, which sits on the visceral surface and isn’t a portal pedicle entry point. This interior, centripetal course within each segment supports efficient vascular and biliary supply to the surrounding hepatocytes.
