In the first convo- luted tubule and the spiral tubule, the cells are cubical and fibrillated, and the lumen is narrow. In the descending limb of Henle's loop and the loop itself, the cells are small and flattened, and leave a larger lumen ; in the ascending limb they become cubical again ; in the second con- voluted tubule, they are cubical and fibrillated ; in the junctional tubule, flat- tened ; in the collecting tubule, clear and cubical ; and in the duct of Bellini, clear and columnar. The arrangement of the capillary blood- vessels in the kidney is somewhat peculiar, for after being gathered up from the tuft of capil- laries in the glomerulus by a small efferent vessel which leaves the glomerulus, the blood is again distributed to capillaries by the sub- division of this efferent vessel, and the second capillary system so formed surrounds the tubules and runs along- side Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Moore, Benjamin, 1867?-1922.
