The kidney's ability to perform many of its functions depends on the three fundamental functions of filtration, reabsorption, and secretion, whose sum is called renal clearance or renal excretion.

"WebKidney Reabsorption. Once inside the lumen of the nephron, small molecules, such as ions, glucose and amino acids, get reabsorbed from the filtrate: Specialized proteins called transporters are located on the membranes of the various cells of the nephron. These transporters grab the small molecules from the filtrate as it flows by them. " - Reabsorption vs secretion in the kidney
