The classical lobule of the liver is centred around

The "classic" liver lobule is the sixsided polyhedral prism with poal triads (hepatic aery, poal vein, and bile duct) at each of the corners. The vessels of the poal triads send distributing branches along the sides of the lobule, and these branches open into the sinusoids. The long axis of the lobule is transversed by the central vein, and this vessel receives blood from the sinusoids. Interconnecting sheets of hepatocytes are disposed in a radial pattern from the central vein to the perimeter of the lobule. Ref - pubmed.com
