The minute structure of the kidney, which commences in the cortical substance of the organ as the Malpighian bodies, small round masses of deep-red color, averaging about 1/120 inches in diameter, and each consisting of a central glomerulus of vessels and a membranous envelope or Bowman's capsule (c), the latter being the commencement of the uriniferous tubule (d). The renal artery (a) and renal vein (v) are also shown.
