They move in the path from the bloodstream into the tubules, which is in the backward direction of reabsorption. These substances are K+ ions, H+ ions, NH4+ ions, creatinine, urea, some hormones, and some drugs. They are concealed because they can pretend as a natural toxin to us if unnecessary amounts are stored in inside the body.
