The direction of thevessels from the aorta and the vena cava is practically right artery ascends a little to its kidney, its origin fromthe aorta being a little lower down than the left; it is alsolonger than the left, owing to the position of the aorta to theleft of the middle line. The right artery passes behind the venacava. Just before entering the hilum, where the vein lies infront and the ureter behind, the artery breaks up into four orfive branches, which are distributed to the renal tissue. Thesebranches mostly, but not uniformly, retain their position behindtheir corresponding veins. Small branches are given off to thesupra-renal body, the ureter, and the neighbouring connectivetissue. The renal veins are a good deal larger than the arteries,and overlap them. The left vein is longer than the right, havingto cr
