A) Hepatic vein, hepatic artery, and bile duct

B) Hepatic artery, portal vein, and bile duct

C) Hepatic vein, hepatic artery, and portal vein

D) Left portal vein, left hepatic artery, and ligamentum teres

E) Porta hepatis, MPV (Main Portal Vein), and CBD (Common Bile Duct)

Answer 1

The portal triad consists of the hepatic artery, portal vein, and bile duct, all of which are essential for liver function and are located within the porta hepatis.

Step-by-step explanation:

The structures that compose the portal triad are crucial in the vascular and biliary anatomy of the liver. The correct answer to which three structures compose the portal triad is B) Hepatic artery, portal vein, and bile duct. The hepatic artery provides oxygenated blood from the heart, the portal vein brings in partially deoxygenated blood containing nutrients from the gastrointestinal tract, and the bile duct is the passage for bile produced by hepatocytes. These three components are all found in the porta hepatis, the central area of the liver where these vessels and ducts enter or leave.
