Each branch of afferent arteriole continues, without anastomoses with the others, until all join to form efferent vessel. Afferent arteriole is larger than efferent one. (After Vimtrup.) the pelvis, or enlarged end of the ureter, which, by way of the bladder and urethra, establishes a highway of communication with the outside world. The blood stream passes through the kidney in the following manner (Fig. 366). It enters at the hilus by way of the renal artery that subdivides in the columns of Bertini into arterioles and finally into arterial capillaries. The latter knot up into the glomeruli, which are entirely arterial, forming a rete mir- abile, rather than an arteriovenous cap- illary transition. The afferent twig enter- ing the glomerulus is larger than the efferent twig which makes its exit near by, on the same side that the afferent twig enters. The inequality in the size of these twigs tends to build a pressure within the glomerulus that is probably higher than in any other capillaries. The emerging efferent twig soon breaks up into a capillary network which entangles the convoluted tubules. Here in this cap- illary network the arterio-venous transition occurs, since at this point intimate contact with the glandular walls of the convoluted tubules occurs, which makes possible the change in the blood from arterial to venous character. The venules emerging from the capillary network anastomose with neighboring venules from other units in the columns of Bertini between the Malpighian pyramids, finally joining to form the renal vein that emerges from the kidney at the hilus. The cortical region presents to the naked eye a granular appearance because in it are embedded the gl
