Storage in the kidneys is associated primarily with the cells of the nephron (the functional unit for urine formation).
-
In some cases, large molecules (including some that are protein-bound) may be secreted (by passive transfer) from the blood across capillary endothelial cells and nephron tubule membranes to enter the urine.
-
Secretion, which occurs in the proximal tubule section of the nephron, is responsible for the transport of certain molecules out of the blood and into the urine.
-
The nephron has three primary regions that function in the renal excretion process, the glomerulus, proximal tubule, and the distal tubule.
