This micrograph includes portions of several glomerular capillaries. stratum corneum stratum granulosum stratum spinosum capillary venule melanocyte? stratum basale dermis blood vessel u lymphocyte infiltrate blood vessel blood vessel vessel blood vessel vessel nerve artery vein blood vessel blood vessel blood vessel blood vessel fibrous connective tissue adipocyte adipocyte adipose tissue nerve blood vessel

The wall of each glomerular capillary consists of capillary endothelium, the filtration membrane, and pedicels of podocytes.

During glomerular filtration, plasma fluid passes through the filtration membrane from capillary lumen into Bowman's space.  The filtration membrane holds back plasma proteins; water and other small molecules pass freely through.
