It is the tubular secretion of H+ and NH 4 + from the blood into the tubular fluid that helps to keep blood pH at its normal level—this Tubular secretion is the transfer of materials from peritubular capillaries to the renal tubular lumen; it is the opposite process of reabsorption. Physiology of Urine formation There are three stages involved in the process of urine formation. Tubular secretion is the process by which the renal tubules actively transport substances from the peritubular capillaries into the tubular lumen. This process Kidney function is most commonly monitored using estimated glomerular filtration rate (eGFR) and albuminuria, which are markers of glomerular function. A.
