Now, these cells, shown in brown, are the potocides. They form the visceral layer of the Bowman's capsule. And these poticides have small extensions that extend into the basement membrane and connect with that basement membrane. And between the potocides, we have these very tiny slits, very tiny holes that also allow the movement of small particles across the membrane. So we have a three layer filtration membrane that allows the movement of certain type of particles across our membrane and into the space of the Bowman's capsule. Now, this type of filtration process that takes place inside the renal corpuscle is known as ultra filtration or glomeryl filtration.
