Inner area of the renal medulla. 0.5 µm thick section of material embedded in plastic, stained with a silver method. Several cross-sectioned Bellini ducts are seen. They are lined by a tall, simple prismatic epithelium that, at this point, is made up of only clear main cells. The space among the ducts is occupied by very thin tubules, in which two types are distinguished. One, the most abundant, is lined by a very thin simple squamous epithelium (endothelium); They are blood vessels, both capillaries and venules. The second type is smaller in diameter and has a higher epithelium: they are loops of Henle.
