The Normal Adult Human Liver Biopsy: A Quantitative Reference Standard

Fig. 2. Venn diagram depicting the number of portal tracts per biopsy containing bile ducts (BD1), hepatic arteries, and portal veins. As portal tracts were defined as having at least two profiles (see Methods), portal tracts with bile ducts, hepatic arteries, or portal veins alone contained at least two of these classes of structures. This diagram depicts only the distribution of bile ducts (BD1) within portal tracts, and does not include the distribution of probable canals of Hering (BD2) profiles (see Patients and Methods for definitions).
