FIGURE 16.5 | Hepatic (Liver) Lobule (Sectional

View, Transverse Section)

A section of the hepatic lobule between the central vein (9) and connective
tissue interlobular septum (1, 6) of the portal area is illustrated in greater detail.

In the interlobular septum (1, 6) are seen portal vein (4), hepatic arteries (3),
bile ducts (5), and a lymphatic vessel (2). Multiple cross sections of hepatic
arteries (3) and bile ducts (5) are attributable to their branching in the septum or
their passage into and out of the septum.

Branches of the portal vein (4) and hepatic artery (3) penetrate the

interlobular septum (1, 6) and form the sinusoids (8, 10) that are situated
between plates of hepatic cells (7). Discontinuous endothelial cells (10) line the
sinusoids (8, 10) and the central vein (9). Blood cells (erythrocytes and

leukocytes) in sinusoids (8) drain toward the central vein (9) of each lobule.
Also present in the sinusoids (10) are fixed macrophages, the Kupffer cells (see
Fig. 16.7).
