Kidney function begins with glomerular filtration, which occurs as fluid from blood plasma crosses the filtration membrane within the renal corpuscle.  In order to be filtered out of the blood, particles must be small enough to pass through two sets of openings: (1) Filtration pores within the endothelium of the [type] capillaries of the glomerulus. (2) Filtration slits formed by foot processes extending from [cells] of the Bowman’s capsule.
