Kidney 26. Inner zone of renal medulla.

Human, fixation with Bouin’s fluid, embedding with paraffin, M-G stain, x 75.

Here, in the inner zone of the renal medulla, three kinds of urinary tubules are seen, i.e.

the thin and thick portions of loop of Henle, and the collecting tubules. Since only thick

portions of loop of Henle stain reddish, the inner zone appears as a whole less reddish-

but rather greenish because of plenty of the connective tissue.----------------------------------
