Verified step by step guidance

Understand the anatomy of a hepatic lobule: A hepatic lobule is the functional unit of the liver, consisting of hepatocytes arranged in plates radiating outward from a central structure.

Identify the central structure: The central vein is located at the center of the hepatic lobule and is responsible for collecting blood from the sinusoids, which are small capillary-like vessels that run between the hepatocyte plates.

Differentiate the portal triad: The portal triad is located at the periphery of the hepatic lobule and consists of three structures: a branch of the hepatic artery, a branch of the portal vein, and a bile duct.

Clarify the role of sinusoids: Sinusoids are specialized capillaries that allow blood to flow from the portal triad toward the central vein, facilitating nutrient and waste exchange with hepatocytes.

Summarize the correct answer: The central vein is the structure located at the center of the hepatic lobule, distinguishing it from the portal triad and sinusoids, which are peripheral or distributed within the lobule.
