KIDNEY. 



uriniferous tubule has no branches between the capsule and the collecting 

 tubule, but there are many branches connected with the latter, as shown 

 in the figure. The rounded "tuning fork" crotches have become angular. 

 The straight tubules, including Henle's loops and the collecting tubules, 

 constitute the medulla and radiate part of the cortex. The remainder of 

 the cortex (pars convolute,} [labyrinth] contains the capsules together with 

 proximal and distal convoluted tubules and arched collecting tubules.

Henle's loop. 



Arciform vein. Arciform artery. 



FIG. 285. PART OP A RADIAL SECTION OP A HUMAN' KIDNEY, x 25. 

 At x a renal corpuscle has dropped out. 



Since a radial section of the kidney shows both the cortex and the 

 medulla, it is the kind made for pathological examination. Under low 

 magnification such a section is shown in Fig. 285. The renal corpuscles 

 [Malpighian corpuscles] are the glomeruli together with their capsules. 

 With higher magnification the various tubules of the radiate portion may
