B)H+ pumping to control pH
C)reabsorption
D)filtration
E)secretion

Question

Quizplus · Accepted Answer

Filtration is the least selective process of osmoregulation by the kidney, as it involves the non-discriminatory removal of water and solutes from the blood into the renal tubules based on their size and charge. Reabsorption and secretion are more selective, involving the active transport of specific substances across the tubule walls, while salt and H+ pumping are highly selective mechanisms that exert fine control over the osmolarity and pH of the body fluids.
