| Description: | The glomerulus is made up of a capillary plexus. Here you can see the
red blood cells in the capillaries. The arteriole associated with the
glomerulus is probably the afferent vessel, judging by its size. The
proximal convoluted tubules have cuboidal cells with eosinophilic
cytoplasm and brush border at the apical surface. The distal tubues
have smaller cells, light cytoplasm and 'clean' lumens due the the lack
of long microvilli. The peritubular capillary network is obvious due
the the brightly stained red blood cells in them. The endothelial cells
of the capillaries produce the hormone erythropoitein. Original
