The spheroidal renal corpuscles (C) are easily identified.

The rest of the tissue is composed of tubules that belong to nephrons, some of which are convoluted (arrows), while others are straight and form parallel fascicles (arrowheads). These fascicles are called medullary rays although they are located in the cortex but are in continuity with the medulla.

The details of the various types of urinary tubules, not seen at this low magnification, will be examined at higher magnifications in subsequent images.
