KIDNEY ULTRASTRUCTURE 



Fig. 2. Tangential secuon ut a glomerular capillary. The epithelial cells or podocytes (Ep) send out 

 numerotis processes, the pedicles, (Ped) which leave a slit-pore (arrow) between them, continuous with 

 the space of Bowman's capsule (B). The pedicles attach at the capillary basement membrane (BM). 

 The capillary endothelium is thin (En) and perforated by abundant pores. In the lumen of the capillary 

 (Lu) small particles in the blood plasma have taken up stain with osmiimi tetroxide. Magnification
