HISTOLOGY AND SECRETION. 5 The vascular supply of the kidney is in intimate relation with theuriniferous tubules. The renal artery divides into a number of branches,known as the interlobar arteries, which, upon reaching the boundaryzone between the cortical and medullary substance, bend sharply andproduce the arterial arches. Each artery is accompanied by a vein, the.

URINARY ANALYSIS AND DIAGNOSIS. The afferent vessel breaks up into a number of small branches which inturn give rise to groups of capillaries forming the glomerulus. Large!capillaries, arising from the smaller, unite to form the efferent vessel,which leaves the glomerulus near the entrance of the afferent vessel, and [i eonsis smaller than the latter. The entire blood supply of the glomerulus is |
