Sources of arterial vascularization of the oviduct in the Italian goose

Abstract

The vascular system has significant physiological lability for timely blood flow and filling the walls with nutrients, therefore, the functioning of the oviduct is closely related to the activity of blood vessels. An important role in this belongs to the arterial system, which performs transport, trophic, homeostatic, protective, excretory functions and gas exchange. The Purpose of our research is to study the sources of arterial vascularization of the oviduct in the Italian goose. The objects of the study were carcasses of Italian goose (female) at the age of 160-180 days in the amount of 5 pieces. In the studied bird species, extraorgan (cranial, middle and caudal protein, cranial and caudal uterine), main (dorsal and ventral oviducts), and intraorgan (craniolateral right and left, caudoventral, and cranioventral uterine) arteries participate in oviduct vascularization. Arterial vessels are involved in intensive blood supply to each part of the oviduct, which performs strictly defined functions. The General principle of vascularization of the oviduct, as a tube-like organ, is that all the arteries entering from its dorsal edge participate in the formation of the dorsal oviduct artery, which runs parallel to its long axis, and the ventral edge passes the ventral oviduct artery. From these arteries, vessels extend to the lateral surface of the oviduct, covering it in a ring-like manner and forming many anastomoses between them.
