Proximal Convoluted Tube is-Fluid in the filtrate entering the proximal convoluted tubule is reabsorbed into the peritubular capillaries. This is driven by sodium transport from the lumen into the blood by the Na+/K+ ATPase in the basolateral membrane of the epithelial cells.tructure and appearance The most distinctive characteristic of the proximal tubule is its brush border (or striated border).
