The main idea is that the main portal vein approaches the porta hepatis from the posterior aspect. As it ascends into the liver, it sits behind the hepatic artery and bile duct and tends to align a bit to the right side and slightly higher relative to the hilum. That’s why entering the porta hepatis is described as rightward, cephalic, and slightly posterior. This posterior entry orientation is a key spatial cue you can use when tracing the portal triad in ultrasound or dissections.
