Which structures comprise the portal triad within the liver?

Explanation:
The structures in the portal triad are the hepatic artery proper, the portal vein, and the bile duct. These three travel together in the hepatoduodenal ligament within the porta hepatis, forming a bundled arrangement that supplies the liver with oxygenated blood (hepatic artery), brings in nutrient-rich blood from the gut (portal vein), and carries bile away from the liver (bile duct). The hepatic veins and lymphatic vessels are not part of this triad; hepatic veins drain blood from the liver to the inferior vena cava, and lymphatics are separate vessels.
