Which histological feature is characteristic of liver tissue?

• A. Hepatocytes arranged in plates around a central vein
• B. Renal glomeruli in corpuses
• C. Lymphoid follicles
• D. Alveolar sacs

Answer: (A)

In liver tissue, hepatocytes are organized into plates (cords) that are essentially one cell thick and radiate outward from a central vein. These plates are separated by sinusoids, which allow blood to flow and come into direct contact with hepatocytes, enabling exchange of nutrients and toxins. At the margins of each liver lobule, you also have portal triads consisting of branches of the portal vein, hepatic artery, and bile duct. This arrangement around a central vein—the plates of hepatocytes surrounding the central vein—is the hallmark feature that identifies liver parenchyma.

That’s why this option is the best fit. Renal glomeruli belong to kidney cortex structures, lymphoid follicles are found in lymphoid tissues like lymph nodes and spleen, and alveolar sacs are characteristic of lung tissue.
