Abstract
Introduction: The formation of the liver structure at mammal embryogenesis is interconnected by drawing up of venous mains. In parallel to the transformation of the main veins, there is a reduction of the blood formation function and the liver transformation from the primary organ of embryogenesis into the secondary one, but the exception is immaturity and underdeveloped maturity mammals (Smirnova, 1967; Mechtiev, 1968; Bresler, 1993). The purpose of research is to establish morphofunctional criteria of the incompleteness in the blood vessels and in tissue components of the liver in neonatal animals.
