"The spinal column below the twelfth dorsal vertebra at <em>A</em> has been removed, as well as the various layers of the great muscles of the back. The two kidneys with the renal arteries and veins are plainly shown, in their normal positions. The relative positions of adjacent vessels and organs with their names printed upon them are also shown. <em>B</em>, portion of the diaphragm on the left side; <em>C</em>, receptaculum chyli; <em>D</em>, a part of the small intestine on the left side." — Blaisedell, 1904

Plan of the blood vessels connected with the tubules. "The blood passes downwards in straight vessels between the uriniferous tubules, to be returned by more or less straight veins to the venous arches, whence it is conveyed by large branches into the renal vein, which leaves the kidney at the hilus and pours its contents into the inferior vena cava... Urine is secreted from the blood in two ways. It is partly removed by a process of transudation or filtration, and partly by the secretary action of the cells lining the uriniferous tubules." &mdash;Kimber, 1907.
