So this is a cross section of the distal convolute. It's coming out of the board and bringing blood this way. Now, these cells are the granular cells, also known as the juxtaglomeral cells, and these are the agranial cells, also known as the laces cells. And we'll talk about the function of these cells in just a moment. So let's take a look at our filtration layer. So if we take a cross section, if we look at this section here, we get the following diagram.
