Longitudinal section,
showing the different renal zones : cortex, outer stripe and inner stripe of the outer medulla, and inner medulla (see diagram on picture 3). When injected intravascularly in vivo, Alcian Blue stains mainly the glomeruli (in the cortex), the vascular bundles in the outer medulla, and the vasa recta at the tip of the papilla.
