WebbSecretion – waste products such as urea and uric acid, drugs and hydrogen and bicarbonate ions are move out of the peritubular capillaries into the filtrate; this removes unwanted wastes and helps regulate pH. Urine – filtrate after it has passed through the nephron and undergone filtration, reabsorption, and secretion. WebbWater is also independently reabsorbed into the peritubular capillaries due to the presence of aquaporins, or water channels, in the PCT. This occurs due to the low blood pressure and high osmotic pressure in the peritubular capillaries. However, every solute has a transport maximum and the excess is not reabsorbed. Webb12 mars 2024 · Peritubular capillaries envelope all of the convoluted tubules of the cortex and recover the materials (water, ions, nutrient molecules) which are pumped across the tubular epithelium.
