FIGURE 18.2 ■ Histologic comparison of blood vessels, the different tubules of
the nephron, and the collecting ducts.
The renal tubule that starts at the renal corpuscle is highly twisted, or tortuous,
and is therefore called the proximal convoluted tubule. Initially, this tubule is
located in the cortex but then descends into the medulla to become continuous
with another tubule, the loop of Henle. The loop of Henle consists of several
parts: a thick descending portion of the proximal convoluted tubule, a thin
