We have a layer of endothelial cells that contain tiny pores, and we have a layer of potocides that contains tiny slits. And these tiny pores and slits allows the movement of only relatively small particles and molecules across our membrane. And this basement membrane contains an overall negative charge and it basically allows the movement of positively charged ions and molecules across the membrane. So we conclude that things like sodium ions, potassium ions, amino acids, glucose, water, very small proteins and urea are all going to be filtered across this membrane. But large proteins such as albumin, red blood cells or platelets these things will not be able to pass across these small holes and they will remain inside the blood vessel and will eventually go into our Ethernet arterial and will return to the blood system of our body. And by this method, our renal corpuscle is capable of filtering and removing some of that waste products from the blood plasma and into the filtrate.
