A contribution to the study of arterial and venous vascularization of the kidney hilus in zebu cattle (Nelore breeding)

Abstract

This paper objetived to contribute to the knowledge of the arterial and venous elements in domestic animals kidneys. So, we have utilized 30 pairs of kidneys obtained from adult bovines 15 males and 15 females Nellore breed. After fixation in formol solution (10%), the dissections are made to see the number and pattern of the vascular branches. Concerning the right kidney, the arterial branches numbered from 3 to 8, with predominance of 4; and at the left one from 3 to 9, with predominance of 4 about the venous roots, in the right kidney, they numbered from 2 to 10 , with predominance of 5, and in the left kidney, from 3 to 10, with predominance of 6 . Generally, the arterial branches and venous roots have showed at the hilus, peripherical situation. The statistical analysis didn't show differences concerning the sexes.
