Resources of venons drainage of heart of peking ducks

Abstract

The paper explores peculiarities of Pekins’ heart vesels. The authors investigate Pekins’ heart venous drainage and conduct their experiment on 10 Pekins’ males and 10 females aged 75 days. The object of research was heart corrosion specimens. The authors used the complex of morphological research methods as Vorobiev’s method of general and thin section, filling of vessels with synthetic SK-65 latex and corrosion specimens preparation. The authors found out that Pekins’ heart vessels are divided into intramiocardial and subepicardial that form well-developed venous pool. Intramiocardial vessels provide intraorgan venous drainage from deep layers of miocardium and flow into subepicardial vessels (middle, left and right) that are under the epicardium. Intraorgan venous bed of Pekins has many anastomoses in all miocardium layers. The authors observed two ways of venous drainage in the Pekins heart. The first way include middle, right and left circuit and left heart vessels that flow into left vena cava cranialis. The second way include right heart vessels that flow into the right atrium. The vessels that flow into the left vena cava cranialis are the main ways of drainage from heart and foster blood distribution in myocardium and its drainage from heart.
