Bowman capsule encloses a tuft of capillaries (glomerulus). Surrounding tubules: PCT (eosinophilic, brush border) + DCT (smaller, no brush border).
Labeled regions (4)
- 1Glomerular capillary tuft
Site of ultrafiltration.
- 2Bowman space
Filtrate collects here before entering PCT.
- 3Proximal convoluted tubule (PCT)
Tall cuboidal with brush border + abundant pink cytoplasm.
- 4Distal convoluted tubule (DCT)
Smaller, no brush border, clearer lumen.
