Renal Cortex, convoluted tubules
Click on a tubule for identification. Click on the thumbnail at right for a labelled image.
Cells comprising proximal tubules stain more intensely eosinophilic than those comprising distal tubules, and have nuclei spaced somewhat farther apart. The lumens of distal tubules commonly appear more open and clear than those of proximal tubules.
Because the proximal convoluted tubule is considerably longer than the distal convoluted tubule, a typical section of the renal cortex includes many more profiles of proximal tubules than of distal tubules.
Cortical stroma, including peritubular capillaries, is generally inconspicuous. The dense, flattened nuclei in this image are those of stromal fibroblasts and capillary endothelium.
