During the histology lecture, the professor highlighted the portal triad at the corners of the hepatic lobule to explain how blood supply and bile drainage are organized.

The pathologist examined the biopsy slide and noted focal inflammation surrounding several portal triads.

Elevated portal venous pressure can lead to variceal bleeding in cirrhotic patients.

During the dissection lab, the students carefully traced the hepatic portal veins to study blood flow from the intestines to the liver.

During the surgery, the surgeon carefully inspected the hepatic portal vein to locate the source of bleeding.
