Renal Tubules (Medium Power)
NOTE:
In this medium-power view of kidney tubules, you can see long, thin spaces (the tubules), lined by simple cuboidal epithelium. Some of the tubules are cut in cross-section, giving them a circular appearance. Contrast these circular structures (with a hollow center) with the round glomeruli, which are larger, and are solid in the center (shown in the next views).
