PECULIARITIES OF HEPATIC VEIN RAMIFICATIONS OF PECKING DUCK

Abstract

The article studies peculiarities of venous drainage from Pecking duck hepar. The researchers apply morphological methods including corrosion specimen in order to investigate hepatic veins. The authors find out right hepatic vein, left hepatic vein and many tiny veins flow into caudal vena cava at an acute angle. They reveal that caudal vena cava consists of intra-organ part and extra-organ part and flows into the right heart atrium. The cranial hepatic vein, craniolateral hepatic vein, medial one and caudal vena cava shape the right hepatic vein. The cranial hepatic vein, craniolateral hepatic vein, the lateral one, medial hepatic vein, cranioventral one and caudal ventral hepatic vein shape the left hepatic vein. The paper notes the common in ramifications topography and peculiarities of venous drainage from hepar by means of the right hepatic vein and the left one; it depends on the organ peculiarities and its functions. The authors reveal general regularities in intra-organ hepatic veins ramifications where blood enriched with metabolic products circulates. The research clarify peculiarities of hepatic veins ramifications of Pecking duck.
