The course and branching of the extraorgan veins of the organs of urination in the arctic fox

Abstract

When keeping fur-bearing animals, it is necessary to take into account that these animals have increased motor activity when they are in natural biogeocinosis. Due to the fact that these representatives of fur-bearing animals are kept in conditions of inactivity, this can inevitably lead to changes in the structure of the cardiovascular system. The purpose of the study is to study the features of the course and branching of extraorgan veins of the organs of urination in Arctic foxes, to determine the morphometric data of these vessels. The objects for this study were the corpses of female arctic foxes of two age groups: newborns and three to four months, five in each group. To achieve this task, a set of traditional anatomical research methods was used. According to the results of the study, it was found that the course and branching of the extraorgan vessels of the organs of urination in female arctic foxes is different. The main outflow of blood from the kidneys are the right and left renal veins; from the ureter – the cranial and caudal branches of the ureter; from the tip of the bladder – the cranial cystic vein; from the body and the bottom of the bladder is the caudal cystic vein. It is also necessary to note the close relationship of the organs of urination with the reproductive system, since the left renal vein communicates with the ovarian. In addition, we have established the presence of rare valves in the veins of the ureters and bladder, and the absence of such in the vessels of the kidneys. Thus, based on linear parameters, it can be concluded that the diameter of the veins gradually increases with the growth of the animal, especially by the period of maturation and intensification of organs.
