WebNov 1, 2024 · An alternative term for centrilobular is pericentral or perivenous. Considering that a human liver has at the minimum 25 cells making up the centro-portal axis, the centrilobular zone and periportal zone each would contain 7–8 cell layers and the intermediate midlobular zone would contain 10 cells (Mak & Png, 2024). In mice, while … WebZone 1 is defined as the periportal area, where functions such as gluconeogenesis, cholesterol biosynthesis, fatty acid β-oxidation and ureagenesis predominate. Zone 3 is the perivenous area (surrounding the central vein), where glycolysis, bile acid biosynthesis, glutamine synthesis, and xenobiotic metabolism occur.
