Filtration slits

From Wikipedia, the free encyclopedia

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 diaphragms.

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