I believe that secretion into the tubular fluid occurs when the principle cells in the Proximal convoluted tubule secrete H + into the urine.

Tubular secretion is the transfer of materials from peritubular capillaries to the renal tubular lumen; it is the opposite process of reabsorption. This secretion is caused mainly by active transport and passive diffusion.
