Features of the branching of the venous vessels of the oviduct and kidneys in the Highsex White cross

The Aim of our research is studying of features of branching of the venous vessels of the oviduct and kidneys in chickens of the cross "Hajseks white". The objects of the study were the carcasses of adult chickens at 160-180 days of age. To study the veins, the method of pouring through the femoral vein with latex brand SCS-65 followed by fixation in a 4% aqueous solution of formaldehyde was used. As a result of our research, we found that the veins of the oviduct are divided into extra - and intra-organ. Extraor-ganic veins (cranial jajtsevidnaja, the average jajtsevidnaja, jajtsevidnaja caudal, cranial uterine) collect venous blood from the funnel, Magnum, isthmus, uterus and vagina. Intraorgan the venous bed of the oviduct consists of macroscopically visible tributaries 5-1 orders of magnitude, forming many anastomoses. Venous blood vessels of the kidneys have a closed annular shape formed by connecting right and left caudal renal portal vein in the posterior part and the anterior - right and left cranial renal portal veins. Renal veins collect filtered through the renal parenchyma venous blood from the middle and caudal parts of the kidneys. Blood is collected from the cranial part along the cranial portal vein and flows into the vertebral venous sinus. Venous blood from the kidneys simultaneously flows through three different vessels: the first way - through the cranial portal vein from the cranial lobes of the kidneys, the outflow of venous blood is carried out into the internal vertebral sinus; the second on the right and left renal portal veins, the blood flowing through the renal parenchyma, forming a double network of capillaries from the renal veins, forming a double supply otlichny the mechanism of movements and the intensive filtration of venous blood through the kidneys; third, outflow is noted on kopchik-mesenteric Vienna in the liver. Features of the location of venous vessels in the serous and muscular membranes indicate a close connection of a certain venous line with each Department of the oviduct, differing from each other in their functional significance.
