About 20% of the blood that enters the globe, marylus, through the Afair Narteriol, is actually filtered into the Bowman space and travels into the proximal convoluted tubule of our nephron. The other 80% basically leaves via the Ethernet arterial and travels to the second capillary network system known as the Vasa rectan. Now, this membrane separating the space of the Bowman's capsule and the space the lumen of the capillaries inside the glomerulus consists of a membrane that has three layers. 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.
