filtration slit

When podocytes contract, they cause closure of filtration slits.

The filtration slits are covered by a diaphragm that includes the transmembrane protein nephrin.

Blood is filtered through these slits, each known as a slit diaphragm or filtration slit.

These pedicels interdigitate with pedicels of adjacent podocytes forming filtration slits.

The podocytes adjoining them have filtration slits of diameter 25 nm that are formed by the pseudopodia arising from them.

Adjacent podocytes interdigitate to cover the basal lamina which is intimately associated with the glomerular capillaries, but the podocytes leave gaps or thin filtration slits.

Bowman's space (or "urinary space", or "capsular space") - Between the visceral and parietal layers, into which the filtrate enters after passing through the filtration slits.

Some studies suggest that the size of the filtration slits restricts the passage of large molecules (e.g., serum albumin) and cells (e.g., red blood cells and platelets).

Foot processes of podocytes interdigitate with one another forming filtration slits (or slit pores) that, in contrast to those in the glomerular endothelium, are spanned by slit diaphragms.

The renal corpuscle filtration barrier is composed of: the fenestrated endothelium of glomerular capillaries, the fused basal lamina of endothelial cells and podocytes, and the filtration slits of the podocytes.
