1904 Excerpt: ...capsule surrounding the glomerulus; 2, neck of the
capsule and beginning of the uriniferous tubule; 3, first
convoluted tubule; 4, spiral portion of the first convoluted tubule
in the medullary ray; 5, descending limb of Henle's tube; 6,
Henle's loop; 7, 8, 9, ascending limb of Henle's tube; 10,
irregular transition to the second convoluted tubule; 11, second
convoluted tubule; 12, transition from second convoluted tubule to
the collecting tubule: 13, 14, collecting tubule, joined below by
others to form the excretory duct, which opens at the apex of the
pyramid. tubule, it will be best to complete this general sketch by
considering the course of the bloodvessels. As has already been
said, the vessels enter the kidney between the calices and pyramids
and are distributed in brandies that lie Fig. 140. parallel to the
bases of the latter, and, therefore, to the convex surface of the
organ, and are situated in the boundary-zone. The arterial branches
in this location form the "arterial arcade." From this arcade
perpendicular branches, the "interlobular arteries," pass toward
the capsule, taking a straight course through the labyrinth between
the medullary rays. In this course they give oif branches, the
"afferent vessels," which go to the Malpighian bodies. Fig. 141.
Fia 140.--Diagram showing the course of the bloodvessels within the
kidney. (Ludwig.) a, interlobular artery; b, interlobular vein; c,
Malpighian body, with the afferent vessel entering it from the
interlobular artery, and the efferent vessel leaving it to take
part in the formation of the capillary plexus between the renal
tubules; d, vena stellata; e, arteriae recta?;/, vena; rectal; g,
capillary plexus around the mouths of the excretory ducts. Fkj.
