MICROANATOMY

Detailed explanation-1: -The liver lobules are a roughly hexagonal arrangement of hepatocyte plates which are separated by intervening sinusoids (small blood vessels similar to capillaries but with a fenestrated endothelium) which radiate outward from a central vein . The portal triads are located at the vertices of each hexagon.

Detailed explanation-2: -The liver lobes are made up of microscopic units called lobules which are roughly hexagonal in shape. These lobules comprise of rows of liver cells (hepatocytes) which radiate out from a central point.

Detailed explanation-3: -The liver lobule is a hexagonal area of tissue, and contains a single central vein which drains blood away from the liver lobule (via the hepatic vein which eventually drains into the inferior vena cava).
