So the glomerulus consists of two types of specialized cells. So lining the capillaries of the glomerulus are cells known as endothelial cells. And endothelial cells are basically involved in filtration. They contain tiny pores, tiny federations that are responsible for allowing the movement of small particles and molecules across this layer and into the Bowman's space. So this region here inside the Bowman's capsule is known as the Bowman's space. Now by the way, this section here is the beginning of the proximal convoluted tubule.
