Which statement accurately identifies the portal triad components in the liver?

• A. Portal triad contains hepatic artery, portal vein, and bile duct.
• B. Portal triad contains hepatic vein, hepatic artery, and bile canaliculus.
• C. Portal triad contains lymphatic vessel, nerve fiber, and artery.
• D. Portal triad contains bile duct, bile canaliculus, and bile salt.

Answer: (A)

The portal triad in the liver consists of hepatic artery, portal vein, and bile duct. The hepatic artery brings oxygen-rich blood to liver cells, the portal vein supplies nutrient-rich blood from the gut, and the bile duct carries bile produced by hepatocytes away to the gallbladder and intestine. Tiny bile canaliculi exist inside liver tissue to drain bile into the bile ducts, but they are not part of the triad itself. Lymphatic vessels and nerves may accompany the triad but aren’t considered components of it. Bile salts are components of bile, not structural elements of the portal triad.
