The center of the lobule is the central vein. At the periphery of the lobule are portal triads. Functionally, the liver can be divided into three zones, based upon oxygen supply. Zone 1 encircles the portal tracts where the oxygenated blood from hepatic arteries enters.

WebJan 1, 2014 · The lobule is divided into three regions ( Figure 13.1 ): (1) periportal (Zone 1) is the closest to the entering blood supply with the highest oxygen tension; (2) centrilobular (Zone 3) abuts the central vein and has the poorest oxygenation; and (3) midzonal (Zone 2) is intermediate.

WebLiver necrosis (whether it appears as ballooning degeneration, apoptotic bodies, or coagulative necrosis) occurs mainly in the centrilobular zones, which leads to dropout and loss of hepatocytes. Extension of hepatocyte injury to the midzonal areas of the lobule leads to the formation of well-demarcated, more or less confluent necrotic areas ... Webthe liver exhibit differential susceptibility to toxins; thus, the site of hepatocyte injury is also an important determinant.12 The centrilobular zone is the most susceptible to chemical-induced liver injury, particularly chemicals that are directly biotransformed to toxic metabolites in the liver as the mature Webcentrilobular (zone 3) receive the least oxygenated blood and are therefore susceptible to hypoxia. Secondly, they have the greatest enzymatic activity, capable of activating compounds into toxic forms ... due to impaired blood flow from the liver: histo - centrilobular fibrosis & siderophages gross - hepatomegaly w/ rounded margins, nutmeg ... lost pubs in blackburn
