12

Which statement best describes the effect diuretics have?

Diuretics increase water reabsorption as a way to decrease the osmolality of the extracellular fluids.
Diuretics promote the formation of the medullary gradient by acting on the ascending limb of the nephron loop.
Diuretics increase urinary output.
Diuretics promote sodium reabsorption and enhance the obligatory water reabsorption that follows.

Diuretics increase urinary output.

True
False

True
