There are two routes for eliminating solutes from the circulation. The first is , which transfers solutes directly from the blood to the tubular lumen, and the other is , which transfers solutes indirectly, from peritubular capillaries to interstitial fluid and from there through tubular cells into the tubular lumen. The second process primarily moves solutes by active transport and is prevalent in the distal convoluted tubules.
