This image shows a
collecting
duct in
the renal medulla. This duct serves as a passageway for urine collected from
several collecting tubules in the renal cortex. The wall is composed of a
simple cuboidal epithelium. On either side of the duct are numerous thin
segments of Henle's loops, lined by simple squamous epithelium with
oval nuclei, and their associated blood vessels, the vasa
recta, lined by endothelial cells with flattened nuclei and containing
eosinophilic erythrocytes.
