PHOTO 18 - Rat kidney

Rat kidney.

Arterial vasculature (white Microfil).

Longitudinal section showing the cortex and outer medulla.

 

From top to bottom, cortex with glomeruli and dense postglomerular capillary network, and outer medulla with vascular bundles issued from the arterioles of the juxtamedullary glomeruli. Note that the upper outer medulla (outer stripe) has a poor arterial vascular bed. The tubules in this kidney zone are mostly supplied with venous capillaries (see picture 19 and 22).
