Kidney - Cortex and Medulla (4x objective lens)


This low magnification view of the feline kidney shows the boundary between the cortex (to the right) and the medulla (to the left). The cortex contains renal corpuscles, convoluted tubules and collecting tubules, whereas the medulla contains the loops of Henle, collecting ducts and papillary ducts (ducts of Bellini). Although not seen in this image, sections through arcuate arteries and arcuate veins can usually be found at the cortex-medulla boundary.
Stain = AZAN.
