While in our distal convolute tubule, we don't have the microvilli on the tube oil epithelial cells. And that's exactly why reabsorption takes place at a much lower rate inside the distal convolute tubule than inside our proximal convolute tubule. In fact, most of the absorption in our nephron takes place within the distal convolute tubule and only about 5% of sodium and chloride is actually absorbed within the distal convolute tubule, as we'll see in just a moment. So the question is, so we know that absorption and secretion takes place within the distal convolute tubule, but what exactly is absorbed and what exactly is secreted and how do these processes take place? So they occur as a result of the different types of protein transporters that are found on the membrane of these epithelial cells. So let's discuss these different types of protein transporters found along our membrane of the cuboidal epithelial cells found in the distal convolute tubule.
