Liver histological structure in adult European bison. Bison bonasus (Linnaeus, 1758)
Folia Morphol 2002;61(3):137-142.
Abstract
The histological structure of the liver in 12 European bison, 2–8 years old, was
presented. The study of the hepatic lobule showed that in Bison bonasus there
were no connective septa around the hepatic lobules. On the hepatic lobule
territory, solitary bile ducts, respectively solitary arterioles, were sometimes observed.
Every one of these vessels was isolated from the hepatic parenchyma by
thick coats of collagen. In the adventitia of the hepatic sublobar vessels, capillaries
of the vasa vasorum system were found. The thick capsule of Glisson presented
an outer part lacking in blood vessels and an inner part vascularised with
arterioles and capillaries originating from the subcapsular portal tracts. The ligament
insertion in the liver parenchyma was described.
