Vascularization of the heart in the American mink

The heart of the American mink is oval in shape, it receives blood supply from the coronal right (d=2 mm) and left arteries (d=1 mm) coming from the ascending part of the aortic arch. The cranial border of the heart is located at the level of 6-7 ribs, and its tip is directed to the left, lies in the region of 8-10 intercostal space. By the nature of the branching of the coronary arteries, the heart of the mink has a left-ventricular type of vascularization, since the left coronary artery feeds most of the organ with blood.
