*the smallest functional unit of the [[Liver - Anatomy & Physiology|liver]] - this unit stresses the dependence of the [[Liver - Anatomy & Physiology|liver]] on its afferent blood vessels and efferent bile ducts
+
*a roughly diamond shaped parenchymal mass surrounding and supplied by the portal area
+
*consists of 3 zones:
+
**Zone 1 - periportal (centroacinar), around the portal areas
+
**Zone 2 - midzonal
+
**Zone 3 - centrilobular (periacinar), bordering the hepatic venules

NB: blood enters from Zone 1 to Zone 3 and thus becomes less and less oxygenated
