And the blood that travels through that glomerulus basically is filtered. So about 20% of that blood enters the space of the Bowman's capsule through a region known as our filtration layer that we're going to discuss in just a moment. And the rest of that blood, about 80% of it, is carried via and into the effing arterial that carries the rest of that blood to the vase erecta, the second capillary system of our nephron. Remember, the nephron contains a portal system, two capillary networks. The glomerolus is the first capillary network and the base erectecta is the second capillary network. So let's take a look at our glomerulus.
