The liver is a vital organ responsible for metabolism, detoxification, bile production, and nutrient storage. Its functional unit is the hepatic lobule, which is a microscopic structural unit composed of hepatocytes arranged in plates around a central vein. Blood flows through sinusoids, allowing efficient exchange of substances between blood and liver cells.

Correct answer: B) Lobule

Why not others?
Acinus: Considered the functional unit based on blood supply (physiological concept), but not the standard anatomical unit.
Sinusoid: Capillary-like blood channels within the lobule.
Hepatocyte: Individual liver cell, not a unit.
