Fig.1 Diagram of kidney structure. The diagram represents
a hemisection of a kidney, revealing its structural organization.
The white dashed line rectangle shows the orientation of
figure2.
Fig.2 NP-1-b Kidney, human, PAS stain. PAS staining is
mainly used for staining structures containing high proportion
of carbohydrate macromolecules, typically found in connective
tissues, mucus, and basal laminae to create a purple-magenta
color. The lower part of the section is the cortex. It is easily
distinguished from the upper portion above the white dashed
line, the medulla. The arcuate vessels are located at the
boundary between the cortex and the medulla.
