Detailed explanation-1: -As noted earlier, the classic liver lobule is a hexagonal solid in which the blood flows from the periphery of the lobule to the center, and bile flows in the opposite direction (Fig. 18.4).
Detailed explanation-2: -A bile duct is part of the portal triad, which enters the liver through invagination of Glisson’s capsule at the hilum. According to the vascular anatomy, the right and left hemiliver are drained by a right and a left hepatic duct, respectively.
Detailed explanation-3: -A portal triad consists of a branch of the hepatic artery, a branch of the portal vein, and a bile duct. DIAGRAM. The acinar concept is now considered to be more useful because it explains the pathology in liver disease better.
Detailed explanation-4: -Hepatic blood flow. In the hepatic lobule, blood enters the lobule via the portal vein and hepatic artery, located within portal triads (PT). This venous and arterial blood then combines and drains through hepatic sinusoids towards the central vein (CV). The direction of blood flow is shown as red arrows.
