The hepatic cells are of more or
less spheroidal form, but may be rounded, flattened, or many-sided from
mutual compression. They vary in size from the n\o to the ~ of an
inch in diameter. They consist of a honeycomb network (Klein) without any cell-wall, and contain one or sometimes two
distinct nuclei. In the nucleus is a highly refracting nucleolus with
granules. Embedded in the honeycomb network are numerous yellow particles,
the coloring matter of the bile, and oil-globules. The cells adhere together
by their surfaces so as to form rows, which radiate from the centre to the
circumference of the lobules.' As stated above, they are the chief
agents in the secretion of the bile.
The Blood-vessels.-The blood in the
capillary plexus around the livercells is brought
to the liver principally by the portal vein, but also to a certain extent by
the hepatic artery. For the sake of clearness the distribution of the blood
derived from the hepatic artery may be considered first.
